A piece of stone of mass 15.1 g is first immersed in a liquid and it weighs 10.9 gf. Then on immersing the piece of stone in water, it weighs 9.7 gf. Calculate the relative density of stone

Text Solution

Verified by Experts

Mass of stone = 15.1 g
Density of stone = Mass of stone / Volume of stone
Or Density of stone = 15.1/5.4
`therefore` Density of stone = `2.8 "g cm"^(-3)`
`therefore` Relative density = Density of stone / density of water = 2.8
