Question

A solid weighs 200 gf in air, 160 gf in water and 170 gf in a liquid. Calculate the relative density of the solid and that of the liquid?​

Answer 1

Explanation:

s,air

= 200 gf

Weight of solid in water W

s,water

= 160 gf

R.D. of solid = W

s,air

/(W

s,air

- W

s,water

) = 200/(200 - 160) = 200/40 = 5

R.D. of liquid = Loss of weight of solid in liquid / Loss of weight of solid in water

= (200 - 170)/(200 - 160) = 30/40 =
