A crystallizer is charged with 8000 kg of an aqueous solution at 104 ° C containing 29.6% Na2SO4 by weight. The solution is cooled. During the cooling, 8% of initial water is lost by evaporation. As a result, the crystals of Na2SO4 × 10H2O crystallize out. If the mother liquor is found to contain 18.2% Na2SO4 by weight. Calculate: (i) The yield of crystals (ii) The amount of mother liquor. Solubility = 4.76g in 100 g of water
