A rock has a volume of 15.2 mL, and a mass of 54.99 grams. Determine its density.

Answer 1

3.62 g/cm^3

Step-by-step explanation:

Density is the ratio of mass to volume:

ρ = mass/volume

ρ = (54.99 g)/(15.2 mL) ≈ 3.61776 g/mL ≈ 3.62 g/mL

Usually, we use cm^3 as the volume unit. Of course, 1 mL = 1 cm^3, so the density is ...

ρ = 3.62 g/cm^3
