Question

An oil of relative density 1.2 and volume 1 litre is poured into water to find the mass of the oil [Ans. 1.2 kg]

Answer

RD of oil = 1.2

Density of water = 1 g/cm3

Volume of oil (V) = 1 lt = 1000 cm3

Step 1: Calculating the density of oil

Density of oil = Density of water × (RD)

= 1 × 1.2 = 1.2 g/cm3

Step 2: Calculating the mass of oil

Mass of oil = Volume of oil × density

= 1000 × 1.2

= 1200 g or 1.2 kg
