Density, Mass Volume Review

Jack has a rock. The rock has a mass of 14g and a volume of 2cm³. What is the density of the rock?

• 7 mL

• 7 g/cm³

• 28 g/cm³

• 1/7 g/cm³

What is the formula for density?

• density = mass x volume

• density = mass / volume

• density = mass + volume

• density = mass - volume
