The solubility of benzoic acid in water is 6.8 g/100 mL at 95 C and 0.3 g/100 mL at 25 C. You are given 10 g of benzoic acid.

The solubility of benzoic acid in water is 6.8 g/100 mL at 95 ° C and 0.3 g/100 mL at 25 ° C. You are given 10 g of benzoic acid. Calculate the amount of water that you would use to recrystallize the sample. If the crystals are collected at 25 ° C what is the maximum possible recovery?
