1. A saturated solution containing 1500 kg of potassium chloride at 360 K is cooled in an open tank to 290 K. If the specific gravity of the solution is 1.2, the solubility of KCI per 100 parts of water is 53.55 at 360 K and 34.5 at 290 K, calculate a. The capacity of the tank required in m'. b. The weight of crystals (kg) obtained neglecting the loss of water by evaporation
