A slice of cheese has a mass of 21 g and a volume of 15 cm3. What is the density of the cheese in units of g/cm3 and g/mL? How can I get g/mL?

Explanation:

First, you have to know the definition of density. Density is mass per unit volume, or D = m/V. In this problem, you are given the mass = 37 g and you are given the volume of 21 cm3. So, the density is simply m/V = 37g/21cm3 = 1.76g/cm3. It's that simple.
