A piece of solid weight 120 g in air, 80g in water & 60g in liquid find the relative density of solid & liquid.

Text Solution

Verified by Experts

Relative density of solid
`= ("weight in air")/("weight in air - weight in water")`
`= (120)/(12 - 80) = 3`
Relative density of liquid
`= ("weight in air - weight in liquid")/("weight in air - weight in water")`
`= (120 - 60)/(120 - 80) = (3)/(2)`
