The density for gold is 19.3 g/cm³. What would be the mass of a 30 cm³ piece of gold?

A. 1,158g

B. 570g

C. 579g

D. 1.55g

C. 579g

Explanation:

Use the formula Density = mass / volume, make mass the subject of the formula and substitute the given values.

19.3g/cm3 is the density of gold

30cm3 is the volume for the piece of gold

The answer is C.

Explanation:

It is given that the formula of density is, ρ = m/v where m is the mass of object and v is the volume of object. By using this formula, you are able to find the mass of gold:

ρ = 19.3 g/cm³

v = 30 cm³

19.3 = m/30

m = 19.3 * 30

= 579 g
