Question

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

Answer 1

Answer:

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

Answer 2

Answer:

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
