gas law

1. IDEAL GAS LAW
The ideal gas law, also called
the general gas equation, is the
equation of state of a
hypothetical ideal gas. It is a
good approximation of the
behavior of many gases under
many conditions, although it has
several limitations.

2. The Ideal Gas Equation is
useful in illustrating the
relationship among the
pressure, volume,
temperature, and number of
moles of a gas. This
equation is used to describe
gases that behave ideally.

3. PV=nRT
where:
V = volume in liters
P = pressure in atmosphere
n = moles
T = temperature in Kelvin
R = universal gas constant,
0.0821 L. atm

4. What is the volume
of a container that
can hold 0.50 mole
of gas at 25.0°C and
1.25atm?

5. If I have an unknown
quantity of gas at a
pressure of 912 mm Hg,
a volume of 31,000 ml,
and a temperature of
87 0
C, how many moles
of gas do I have?

6. Calculate the pressure
exerted by a 0.25 mole
sulfur hexafluoride in a
steel vessel having a
capacity of 1250 mL at
70.0°C.

7. A cylinder of Argon
gas contains 50.0 L of
Argon at 18.4 atm and
127 °C. How many
moles of argon is in
the cylinder?

8. Fermentation of glucose
produce gas in the form of
carbon dioxide, how many
moles of carbon dioxide is
produced if 0.78 L of carbon
dioxide at 20.1°C and 1.00
atm was collected during
the process?
