Mass divided by Volume = Density
Find the density of the crown. 1.Is it real gold? 2.What is your evidence?
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?
The following formulas are for finding different variables in density problems.
m mv D= =
= D vxm
D v
Do you remember the unit labels for each?
Mass Unit Label =
Volume Unit Label =
Density Unit Label =
GRAM
mL, cm3, cc
g/mL, g/cm3, g/cc
The following formulas are for finding different variables in density problems.
m mv D= =
= D vxm
D v
