Answer:

Metal Bob

Heavier body that can dip in water and displace water can be used to find the density by using water.

Materials Required

A spring balance, a measuring cylinder, a beaker with water, a metal bob (or any body that is heavier than water and does not dissolve in water), a cotton string, a stand (optional).

Procedure

Tie a metal bob (or any solid) with the string of cotton to the hook of the spring balance. The spring balance should be checked for any error. Let the zero error be 'x'.

Hold the spring balance (or tie it to the stand), suspended with the metal bob in air. Measure the weight of the bob. Let its weight be ‘WF'

Pour the water in the measuring cylinder and record the initial volume of water, let it be   ‘ V1'

Suspend the metal bob into the measuring cylinder with water. The bob should not touch the base, nor the sides of the cylinder.

The water level rises, measure the increased water level, let this volume be ‘ VF'

Record all your observations in the observation table and do the calculation to find the density of a given solid metal bob.

Example-

Weight of the given Metal Bob = 400N

Mass of the Metal Bob = 400/9.8 = 40.8 g

Volume of water displaced by solid (metal bob) = 20 mL.

Density of a solid (metal bob) =  = 2.04 g/cm3

1 mL of water = 1 cm3

Result 

The density of given solid (Metal Bob) is 2.04 g/cm3
