A 2246 kg feed solution at 324.3 K, containing 48.2 kg of 4/100 kg of total water, is cooled to 282.7 K to extract crystals of 4 72. The solubility of the salt is 30.9 4 /100 kg of total water (PI). The average heat capacity of the feed solution can be assume equal to 2.93 /(HI). The heat of solution at 291.2 K is -13.31 x 103 kJ/kg mol of 4 72(PI). Calculate the yield of crystals and determine the total heat absorbed q, by means of a balance of heat, assuming no water is vaporized.
