Question

a solid X, insoluble in water, weighs 180g in air and 150g in water. what is the relative density of the solid X?


it is the physics question.

Answer 1

densityX=180/v

in water, bouyant force=densitywater*V
or
density water=30/V


So relative density=180/30=6

Answer 2

densityX=180/v

in water, bouyant force=densitywater*V
or
density water=30/V


So relative density=180/30=6
