An impure sample contains 0.74 g of impurities and 4.55 g of benzoic acid. The sample is dissolved in 100 ml of water and heated. The solution is then cooled. How many grams of the impurity will crystallize when the solution has cooled? Include the unit and two decimal places in your answer. The solubilities of the impurity and benzoic acid in cold and hot water are given below. Compound Cold Water solubility Benzoic acid 0.42 g per 100 mL of water 5.79 g per 100 ml of water Impurity Hot Water Solubility 0.61 g per 100 mL of water 4.62 g per 100 mL of water
