Question

What is the volume of a sample of gold if it has a density of 20 g/cm³ and a mass of 40 g?

A.0.5 cm³
B.2 cm³
C.40 cm³
D.800 cm³

Answer 1

What will be the volume of the gold sample, if it has a density of 20 g/cm³, with a mass of 40 g. Therefore, we apply the following formula:

v = d/m

We substitute our data in the formula and solve:

V = 20 g/cm³/40 g

V = 0.5 cm³

If the gold sample has a density of 20 g/cm³ and a mass of 40 g, its volume is 0.5 cm³.Alternative "A".
