Calculating Density
Density = Mass divided by Volume D = M/V
Mass = Density times Volume M = D x V
Volume = Mass divided by Density V = M/D

Density Worksheet
1. Define mass?
2. Define volume?
3. Define density and show the formula for calculating density.
4. Why does changing the shape of an object have no effect on the density of that
object?
5. Aluminum is used to make airplanes. Cast iron is used to make weightlifting
equipment. Explain why the densities of these metals make them useful for these
purposes?
6. What is the density of water? Remember for water 1g=1ml=1cm3
7. Why does an air bubble rise to the surface of a glass of water?
8. Calculate the densities of the following objects. Remember to place units after
each number.
a. Object A length = 6cm, width = 3cm, height = 1cm, mass = 36g
volume = _____ density = _____
b. Object B length = 10cm width = 5cm height = 2cm mass = 300g

9. Which of the following materials will float on water (density 1 g/cm3)?
____air = .001 g/cm3
____corn oil = .93 g/cm3
____glycerine = 1.26 g/cm3
____corn syrup = 1.38 g/cm3
____wood = .85 g/cm3
____steel = 7.81 g/cm3
____rubber = 1.34 g/cm3
____ice = .92 g/cm3
____water = 1.00 g/cm3
10. Assuming the materials don’t mix, show how the materials would "stack up" in a
graduated cylinder.
