A solid of mass 450 kg has a volume of 250 cm3. Calculate the relative
density of the solid. [Density of water
loo kg m-3]
​

0.0018

Explanation:

Given that,

Mass of a solid, m = 450 kg

Volume, V = 250 cm³ = 0.00025 m³

The density of solid is given by :

Density = mass/volume

So,

The density of water is 1000 kg/cm³.

Relative density = density of solid/density of water

So, the relative density of the solid is 0.0018 .
