A hot solution containing 1000 kg of MgSO, and water having a concentration of 30wt% MgSO is cooled to 288.8 K, where crystals of Mg8O.20 are precipitated. The solubility at 288.8 K is 25.4 wt% anhydrous MgSO4 in the solution. Calculate the yield of crystals obtained if 5% of the original water in the system evaporates on cooling.
