The solubility of copper (II) sulphate is 55g/100g of water at 75oC and 19g/100g of
water at 15oC. What mass of crystals would be deposited, if 150g of a saturated solution
is cooled from 75oC to 15oC.

150g of the saturated solution contains 50g of the salt in 100g of water.
Solubility at 15oc is 19g/100g of water
Mass of the salt to crystallized 50g-19g = 31g
