We know that: "Density of substance =("Mass of substance ")/("Volume of substance ")
Here Mass of substance = 50 g
And Volume of substance =20 cm^(2)
So Density of substance =(50 g )/(20 cm ^(3))
=2.5 g cm^(-3)
Since the density of substance (2.5 g cm ^(-3) is greater than the density of water (1 g cm^(-3)), therefore , the substance will sink in water .
