Volume to Find Mass
Problem
Determine the mass of an object that, when placed in a 25-mL graduated
cylinder containing 14 mL of water, causes the level of the water to rise to
19 mL. The object has a density of 3.2 g/mL.
1. Analyze the Problem
Known:
Unknown:
You know the density and the volume of an object and must determine
its mass; therefore, you will calculate the answer using the density
equation.
2. Solve for the Unknown
Write the density equation.
=
Rearrange the density equation to solve for mass.
and
Multiply the values and units. The mL units will cancel out.
mass =

3. Evaluate the Answer
The two sides of the equation should be
density =
