Extracted text: 1. A saturated solution containing 1500 kg of potassium chloride at 360 K is cooled in an open tank to 290 K. If the density of the solution is 1200 kg/m³, the solubility of potassium chloride/100 parts of water by mass is 53.55 at 360 K and 34.5 at 290 K calculate: (a) the capacity of the tank required, and (b) the mass of crystals obtained, neglecting any loss of water by evaporation.
