Solution

We can find the relative density of a solid denser than water by following the experiment.

Weighing a solid in air and water

Find the weight (W1 gf) of a solid in the air using a hydrostatic balance.

Tie the solid firmly with a thread and suspend it from the hook. Lower the solid in water and find its weight.

Record the result as shown below:
Weight of solid in air = w1 gf.

Weight of solid in water = W2 gf.

The apparent loss of weight of solid = (W1 - W2 ) gf.

Relative density = W1/ (W1 - W2)

The relative density of the solid = (weight of solid in the air )/(Apparent loss of weight of solid in water).
