Question

Find the density of a rock that has a mass of 40 g and a volume of 20.5 cm³.

Answer 1

Density is found by dividing mass by volume. The following formula can be used to find the density of an object:

D=
`(m)/(v)`

D=
`(40 g)/(20.5 cm^3)`

D=1.95 g/cm³

The density of the rock is 1.95 g/cm³.
