Question

Gold has a density of 19300 kg/m³. Calculate the mass of 0.02 m³ of gold in kilograms.

Answer 1

d = m/v

m = d*v

m = 19300 * 0.02

= Answer

Answer 2

The mass of 0.02 m³ of gold is 386 kilograms.

Explanation:

Given:

The density of the gold =  19300 kg/m³.

The volume of gold =  0.02 m³

To Find:

The mass of gold  = ?

Solution:

We know that density is mass divided  per unit  volume.

Thus mathematically

$Density = \frac{mass}{volume}$

Rewriting in terms of mass ,

Mass =  density * volume

On substituting the known values

Mass =   19300 kg/m³ *   0.02 m³

Mass = 386 kilograms
