Density Practice: Worksheet #1
Calculate density, and identify substances using a density chart.
Density is a measure of the amount of mass in a certain volume. This physical
property is often used to identify and classify substances. It is usually expressed in
grams per cubic centimeters, or g/cm3. The chart on the right lists the densities of
some common materials.
Equation: Density = mass or D = m
Volume V
Problem Statement Formula Define Variables Substitution Answer
Sample: What is the density of a
billiard ball that has a volume of
100 cm3 and a mass of 250 g?
D = m
V M = 250 g
V = 100 cm3 D = 250 g
100 cm3 2.5 g/cm3
1. A loaf of bread has a volume
of 2270 cm3 and a mass of 454 g.
What is the density of the bread?
2. A block of wood has a density
of 0.6 g/cm3 and a volume of
1.2 cm3. What is the mass of the
block of wood?
3. A 800g boulder has a density
of 8 g/cm3. What is the volume
of the boulder?
4.What is the mass of the block
of iron illustrated below?
Use the data below to calculate the density of each unknown substance. Then use the density chart above to
determine the identity of each substance.
