Question

A solid weighs 120 gf in air and 105 gf when it is completely immersed in water. Calculate the relative density of solid.

March 19, 2024

Answer

Weight of the solid in air (W₁) = 120 gf

Weight of the solid when completely immersed in water (W₂) = 105 gf

RD of solid = $W_1\over W_1 - W_2$

= $120\over 120 - 105$ = 8

∴ Relative density of solid = 8
