An impure sample contains 0.74 g of impurities and 4.55 g of benzoyl 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? The solubility of the impurity and benzoic acid in cold and hot water are given below: Compound/ Cold water solubility/Hot water sol Ben acid/ 0.42 g per 100 mL/ 5.79 g per 100 mL Impurity/ 0.61 g per 100 mL/ 4.62 g per 100 mL   Are the crytals produced pure benzoic acid?
