Given that Mass of substance is = 50g and volume is = 20cm3.
Then the density of the substance will be =
As we know that density of water = 1 g/cm3
According to Archimedes' principle the substances having higher density then water will sink in water & substances having density lower then water will float on the surface of water.
Since the density of the substance is greater than the density of water, it will sink in water.
The volume of water displaced =Volume of substance = 20 cm3
Mass of water displaced By substance = volume × density = 20×1 = 20g
