academic integrity
In the business administration discipline, we have a
commitment to academic integrity and expect students to
maintain the highest level of academic integrity in working
toward a degree.
Students will complete the Academic Integrity Module and then
place the certificate in the Assignment Folder. Please note that
no points are earned toward the final grade but you are expected
to complete the module, submit the Certificate of Completion
and a Statement of Understanding to the Assignment Folder in
Week 1.
The Statement of Understanding is a two paragraph personal
statement that:
· Provides your understanding of Academic Integrity module
· Provides your understanding of what is expected when you
submit any and all work for a grade followed by a statement
that you are committed to upholding academic integrity in
completing all work in the course
This assignment has to be submitted in order to receive a grade
for Assignment 1. Faculty will apply the late assignment policy
to Assignment 1 if the Academic Integrity module certificate
and Statement of Understanding are not submitted to the
Assignment Folder before Assignment 1 is due.
NOTE: ALL OF THE FOLLOWING ARE CONSIDERED
PLAGIARISM:
· copying words or ideas from someone else without giving
credit such as taking information from the Internet and not
citing and referencing;
· using a paper or work submitted by another student and
turning the work in as your own
· using any type of clearinghouse that offers assistance in

writing assignments including learning activities;
· failing to put a quote in quotation marks
· giving incorrect information about the source of a quotation
· changing words but copying the sentence structure of a source
without giving credit
· copying so many words or ideas from a source that it makes up
the majority of your work, whether you give credit or not
· falsifying citations or references
· using phrases, charts, figures, illustrations, or mathematical or
scientific solutions without citing the source
· paraphrasing ideas without citing the source.
Academic dishonesty also includes purchasing or receiving an
assignment from a clearinghouse or taking an assignment
completed by another person or having another person complete
the assignment.

Lab 20: Ideal Gas Law
PV
n =
RT
Once the number of moles of O2 gas is calculated, the percent o
f H2O2 present in the solution can be determined. To do
this, you first need to calculate the theoretical number of moles
of O2 there would be if the solution was 100% hydrogen
peroxide. This can be found by using the following equation:

For this experiment:
H2O2 used is the volume of H2O2 you actually use
(approximately 5 mL).
density is 1.02 g/mL
mol H2O2 / 34.0 g H2O2 is the reciprocal
(inverted
fraction). of the molar mass of H2O2 . The molar mass
of H2O2 is 34.0 g /mol, so this is equal to 1 mol H2O2 /
34.0 g H2O2.
mol O2 / 2 mol H2O2 is used since the decomposition
produces 1 mole O2 from 2 moles of H2O2 .
units in the entire equation cancel to give moles
of O2.
The percent hydrogen peroxide can now be found. To do this,
divide (n), the actual number of moles you calculated, by the

theoretical moles of O2 there would be if the hydrogen
peroxide were 100%. This number is then multiplied by 100%.
This value can now be compared to the 3% hydrogen
peroxide shown on the label to see if any decomposition
has
occurred.

In this experiment, we will use yeast to accelerate the decompos
ition of the hydrogen peroxide into water and O2 gas.
Yeast contains the enzyme catalase, which is a catalyst for this r
eaction. You will add yeast activated in warm water to a
known amount of hydrogen peroxide and quickly seal off the sy
stem so that the O2 gas formed is collected in a graduated
cylinder. After measuring the total volume of gas produced, its
temperature, and the atmospheric pressure, the ideal gas
law can then be used to calculate how many moles of
O2 gas is formed. We can do this by solving the ideal
gas law
equation for n.
Figure 3: Carbonated beverages contain dissolved CO2 at
high pressure. When the container is opened, this pressure
can create a powerful burst, such as with this sparkling
wine bottle, or when your soda “explodes.”

Pre‐Lab Questions
1.
What is it in yeast that aids in the decomposition of hydrogen p
eroxide?

2. List the ideal gas law and define each term with units.
3.
How many moles of O2 were produced in a decomposition react
ion of H2O2 if the barometric pressure was
0.980 atm, the temperature was 298 K and the volume of O2 gas
collected was 0.0500 L?

4.
If you decomposed 10.00 mL of 100% H2O2, how many moles o
f O2 could you theoretically obtain?

Experiment: Finding Percent H2O2 with Yeast
Procedure
1.
Prepare the materials for the apparatus as shown in Figure 1. Ins
ert the smaller rigid tubing into one end of
the larger, flexible tubing. Insert the free end of the rigid tubing
securely into the rubber stopper hole.
2.
Bend the free end of the flexible tubing into a U shape, and use

a rubber band to hold this shape in place.
This will allow you to more easily insert this end of the flexible
tubing into the inverted graduated cylinder.
Make sure the tubing is not pinched and that gas can flow freely
through it.
2. Fill the 600 mL beaker with 400 mL distilled water.
3.
Fill the 100 mL graduated cylinder with distilled water slightly
over the 100 mL mark.

4.
Take the temperature of the water in the 600 mL beaker, and rec
ord it in the Data section. Also, determine
the barometric pressure in the room, and record it in the Data se
ction. HINT: The pressure in your region
may be found online—
if necessary, convert this value to mm Hg.
5.
Mix 100 mL of warm water (45°C) and 1 packet of baker’s yeast
in a 250 mL beaker. This will activate the
yeast from the dormant (dry) state. Be sure to mix well with a st
ir rod until the yeast is completely dissolved.
6. Use a 10 mL graduated cylinder and pipette to

measure out 5.00 mL of hydrogen peroxide. Pour this
hydrogen peroxide into the Erlenmeyer flask, and place the stop
per with stopper tube over the top.
7.
Clean the 10 mL graduated cylinder by rinsing it at least three ti
mes with distilled water. Dispose of the rinse
down the drain.
8.
Cover the opening of the graduated cylinder with two or three fi
ngers and quickly turn it upside down into
the 600 mL beaker already containing 400 mL of water. DO NO
T remove your fingers from the opening until
the graduated cylinder is fully submerged under the water. If th
e amount of trapped air exceeds 10 mL, refill
the cylinder and try again.
9. Insert the U shaped side of the flexible tubing
into the beaker, and carefully snake it into the submerged
opening of the graduated cylinder. You want as little air as poss
ible to be in the graduated cylinder.
10.
Secure the graduated cylinder to the ring stand by sliding a ring

under the submerged cylinder, then attach‐
ing the ring to the stand.
OPTIONAL PROCEDURE: If your kit does not
include a ring stand, you will hold the graduated cylinder in
place while gas is collected. Make sure to keep the open end of
the cylinder completely submerged to pre‐
vent additional gas from entering. Rest the graduated cylinder a
gainst the side of the beaker during experi‐
mental setup.
11. With the cylinder vertical, record the volume of air
inside (the line at which the water reaches in the
cylinder) in the Data section in Table 1.
12.
Using the pipette, measure out 5.00 mL of yeast solution into th
e rinsed 10 mL graduated cylinder. NOTE: Do
not immediately pour the yeast solution into the Erlenmeyer flas
k.
13.
Prepare to place the stopper (still connected to the hose) on the
Erlenmeyer flask. Reset the stopwatch.

14.
Quickly pour the 5.0 mL of yeast solution into the Erlenmeyer f
lask. Immediately place the stopper securely
in the opening of the Erlenmeyer flask by twisting it down into t
he flask gently.
15. Start timing the reaction with the stopwatch.
16.
Swirl the Erlenmeyer flask to mix the two solutions together.
17.
You will begin to see bubbles coming up into the 100 mL gradu
ated cylinder. HINT: If gas bubbles are not
immediately visible, make sure the stopper is on tight enough an
d the tubing is not leaking. You will need to
start over after correcting any problems.
18.
Continue to swirl the Erlenmeyer flask and let the reaction run u
ntil no more bubbles form to assure the
reaction has gone to completion. This should take approximatel
y 6‐10 minutes. HINT: Catalase works best
around the temperature of the human body. You can speed the re
action up by warming the Erlenmeyer flask

with your hands.
19.
Record the time when the reaction is finished in Table 2 of the
Data section, along with the final volume of
air in Table 1. Remember to read it at eye‐level and measure fro
m the bottom of the meniscus.
20.
Pour all other liquids down the drain and clean the labware.

Calculations
The goal is to find the percentage of hydrogen peroxide
in the solution! This can be found by working through
the
following steps.
1.
Convert the temperature of the water from ⁰C to Kelvin (K). Use
the equation K = ⁰C + 273. This will be your
value for absolute T or the temperature in Kelvin.

2.
If necessary, convert the barometric pressure in the room from
mm Hg to atmospheres (atm).
Divide the measured pressure from the Data section by 760 mm
Hg. This will give you pressure
(P) in atmospheres.
T = ⁰C + 273 = K
P = mm Hg * = atm
1 atm
760 mm Hg

3. Convert the volume of oxygen from mL to liters (L).
4. Rearrange the ideal gas law to solve for n.
5.
You are now ready to solve for the number of moles of O2. Be
sure the units cancel so that you end up with
only the moles of O2 left. Use the value for the constant R give
n:

Actual number of moles of O2 (n) = moles
V = mL * = L
1 L
1000 mL
R = 0.0821 L∙atm/mol∙K

6.
Calculate the theoretical number of moles of O2 there would be
if the hydrogen peroxide were 100%, and not

an aqueous solution.
To use the above equation, calculate the following:
—
H2O2 volume is the volume (mL) of hydrogen peroxide used
: Volume = mL H2O2
— H2O2 density is known: Density = 1.02 g/mL
Molar mass of H2 O2 = g H2O2/1 mol H2O2
Molar mass of H2 O2 reciprocal =
Now you have all of the information needed to solve the equatio
n for the theoretical moles of O2. All you need

to do is fill in the blanks and do the calculations.
Theoretical moles of O2 =
Theoretical moles of O2 = mol

Was the calculated percentage of hydrogen peroxide close to the
same as the percentage on the label?

2.
Considering that catalysts are not consumed in a reaction, how d
o you think increasing the amount of catalyst
would affect the reaction rate for the decomposition of hydroge
n peroxide?
