Density Practice Problems
For the problems below, show all work and box your final answers.
1. A platinum bar measures 5.0 cm long, 4.0 cm wide, and 1.5 cm thick. It has a mass of 700.0
grams.
a. Calculate the volume of the platinum bar.
b. Calculate the density of the platinum bar.
2. A lead cylinder has a mass of 540 grams and a density of 2.70 g/ml. Calculate the volume of
the lead cylinder.
m
d
v
Density is the amount of mass per unit volume of a
given object. It can be calculated using the following
equation. d=m/v
If the density of the object and either mass or volume is
known, by rearranging the above equation.
m=d*v
v=m/d
These three equations can be easily remembered
by using the circle below. Simply cover up the
measurement you are trying to solve and you are
left with the mathematical relationship of the
remaining two.
