Explanation / Answer

100mL of boiling water.contains 5.5 g acetanilide

Since the solubility of acetanilide is only 0.53g in 100mL of ice cold water, when this solution is cooled in ice cold water, 0.53 g will remain in solution and (5.5- 0.53) g = 4.97 g will crystallize out.

Percent recovery = (4.97 g/ 5.5g) x100 % = 90.36 %
