Density Practice
Solve the following density questions using the formula: density = mass ÷ volume.
*** Your unit should always be a combination of both mass/volume! Ex: g/cm3 ***
1. What is the density of an object with a mass of 60 g and a volume of 15 cm3?
2. A bottle contains 240 mL of liquid. A student finds that the mass (excluding the
bottle) is 480 g. What is the density of the liquid?
3. Roland has a plastic block that is 90 g. It has a length of 6 cm, a width of 4 cm, and a
height of 5 cm. What is the density of the block?
4. Bob, who has a mass of 75,000 g, found a rock. What is the density of the rock if it
has a mass of 42 g and volume of 12 cm3?
5. If a log of balsa wood has a mass of 1,200 g and a volume of 6,000 cm3, what is the
density of the log?
6. What is the density of a liquid that has a volume of 100 L and a mass of 70 kg?
