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

mystery substance?
2. A diamond with a volume of 2 cubic centimeters has a mass of 7 grams. What is
its density?
3. The density of cork is 0.2 g per cm. If I have a cork with a mass of 0.4 grams,
what would its volume be?

9. You are given a golf ball that has a mass of 30 grams and a volume of 12 cubic
centimeters, and a baseball that has a mass of 350 grams and a volume of 60 cubic
centimeters. Calculate the density of each object to determine which one has the
greater density. Will either sink if placed in a pan of water?
10. Your cell-phone has a mass of 800 g and a volume of 50 cm3. Calculate its
density and compare it to the density of water to determine if it would sink/float if
you dropped it in a pool.
11. Put the following three liquids in order of increasing mass: Liquid A has a
density of 2.4 g/cm3 and a volume of 30 cm3. Liquid B has a density of 2.9 g/cm3
and a volume of 15.0 cm3. Liquid C has a density of 0.36 g/cm3 and a volume of
80 cm3. If you mixed these 3 liquids together what would happen?
