Question

The volume of 50 g. of a substance is 20 cm . If the density of water is 1 g cm^-3, will the substance float or sink?

Answer 1

1. Density of substance = Mass / Volume = 50 g/20 cm³ = 2.58 cm^-3 .

2. Density of water = 1 g cm^-3 . 

As the density of substance is greater than that of water, so, the substance will sink in water.
