The solubility Of KCLO is 33g per dm of water at 70 and 8g per dm of water at 20 calculate the mass of the solute which will crystallize out when 160g of the saturated solution is cooled from 70 to 20
well, only 8/33 will remain, so the remainder 25/33 will crystalize out.
Mass crystalized: 25/33 * 160
