Solution
Mass of the substance = 40 g
Volume of the substance = 20 cm3
Density of the substance = Mass / Volume
= 40 g / 20 cm3 = 2 g/cm3
As the density of the substance (2 g/cm3) is higher than the density of water (1 g/cm3), the substance will sink in water.
Volume of the substance = 20 cm3
Density of the substance = Mass / Volume
= 40 g / 20 cm3
= 2 g/cm3
As the density of the substance (2 g/cm3) is higher than the density of water (1 g/cm3), the substance will sink in water.
As the density of the substance (2 g/cm3) is higher than the density of water (1 g/cm3), the substance will sink in water.
