$ 3.162000 \mathrm{~kg} $ of salt solution containing $ 30 \% $ salt are heated to evaporate a part of $ \mathrm{H}_{2} \mathrm{O} $ and then cooled to $ 20^{\circ} \mathrm{C} $ to crystallize the salt. If $ 50 \% $ of dissolved salt in the original solution is to be crystallized out, calculate: (i) The weight of water to be evaporated and (ii) The weight of mother liquor left after crystallization. Data: Solubility of salt at $ 20^{\circ} \mathrm{C}=\frac{36}{100} \frac{\mathrm{g} \text { salt }}{\mathrm{g} \text { of water }} $.
