Question

The volume of 50g of a substance is 20 cm³. If the density of water is 1gcm^-3 will the substance float or sink?

Answer 1

Mass of a substance = 50g

Volume of substance = 20 cm³

∴ Density of substance, d = \(\frac{Mass}{Volume}\)

= \(\frac{50}{20}\) = 2.5 g cm^-3

i.e., the density of the substance is greater than the density of water. So it will sink in water.
