9. Find the
density of the
crown.
1.Is it real
gold?
2.What is
your
evidence?

10. 1. Identify the type of numbers you have.
(unit labels)
2. Understand what the problem is
asking.
3. It is a one step problem or two step
problem?
4. Which formula should you use?

11. The following formulas are for finding
different variables in density problems.
m m
v = D D = v
m = D x v

12. Do you remember the unit labels for
each?
Mass Unit Label = GRAM
Volume Unit Label = mL, cm3, cc
g/mL, g/cm3,
Density Unit Label = g/cc

13. The following formulas are for finding
different variables in density problems.
m m
v = D D = v
m = D x v
