The solubility of ammonium formate, NH₄CHO₂, in 100. g of water is 102 g at 0°C and 546 g at 80°C. A solution is prepared by dissolving NH₄CHO₂ in 200. g of water until no more will dissolve at 80°C. The solution is then cooled to 0°C. What mass of NH₄CHO₂ precipitates? (Assume that no water evaporates and that the solution is not supersaturated.)
