A piece of solid weighs 120g in air, 80g in water and 60g in a liquid. The relative density of the solid and that of the liquid are respectively:


Open in App
Solution

Step 1. Given data

The weight of the solid in air is given as 120g,

Weight in water is given as 80g,

Weight in liquid is given as 60g.

We have to find the relative density of solid and liquid.

Step 2. Formula to be used.

The relative density of a substance is defined as the ratio of the density of the substance to the density of water. It is represented by symbol R.D.

Thus,

R.D.=DensityofthesubstanceDensityofwater

Step 3. Find the relative density of solid

The relative density of a substance is defined as the ratio of the density of the substance to the density of water. It is represented by symbol R.D.

Thus,

R.D.=DensityofthesubstanceDensityofwater

The relative density of solid is given by:

R.D.=WtairWtair-Wtwater

=120120-80

=3

Step 4. Find the relative density of liquid.

The relative density of liquid is,

R.D.=Wtair-WtliquidWtair-Wtwater

=120-60120-80

=32

Hence, the relative density of the solid and that of the liquid are 3 and 32 respectively.
