Question

Calculate the relative density of copper sulphate solution from the given data.
Mass of empty density bottle = 22.5g
Mass of bottle + water = 47.5g
Mass of bottle + copper sulphate = 52.5g
Density of water 1g/cm 3

Answer 1

Explanation:

Mass of empty density bottle = 30 gm

mass of density bottle with water in it 62 gm

Mass if density bottle with the liquid = 54 gm

Mass of water only = 62-30=32 gm

(a) Now volume of 1 g of water = 1cm

3

∴ Volume of density bottle = 32 cm

(b) Mass of liquid only = 54-30=24 gm

∴ density of the liquid = ∴
