If a sample of metal weighs 210 gm in air, 180 gm in water and 120 gm in a liquid:
Relative density of metal is 3
Relative density of metal is 7
Relative density of liquid is 10
Relative density of liquid is 13
Relative density of metal=210210−180=7
Relative density of liquid=210−120210−180=3
A sample of metal weighs 210 gm in air, 180 gm in water and 120 gm in liquid. Then relative density (RD) of
