The solubility of benzoic acid in water is 0.18 g/100 ml at 0oC and 6.7 g/100 ml at 100oC. Answer the following questions if 5.96 grams of benzoic acid were to be heated to boiling in 100 ml of water. What would be the maximum possible percent recovery if the solution was cooled to 0oC and vacuum filtered? Put your answer in 3 significant figures.
mass of solid left = 5.96 - 0.10
= 5.86 g
percent recovery =( mass of solid left / total mass ) x 100
= (5.86 / 5.96) x 100
= 98.3 %
