A feed solution of 2268 kg at 327.6 K containing 48.2 kgMgSO/100 kg water is cooled to 283.2 K where MgSO4.7H₂O crystals are removed. The solubility of the salt is 30.9 kg MgSO/100 kg total water. The average heat capacity of the feed solution can be assumed as 2.93 kJ/kg-K. The heat of solution at 291.2 K is -13.31x 103 kJ/kg mol MgSO4.7H₂O. Calculate the yield of crystals and make a heat balance to determine the total heat absorbed, q, assuming that no water is vaporized.
