The solubility of acetanilide in hot water (5.5 g/100 mL at 100) is not very great, and its solubility in cold water (0.53 g/100 mL at 0) is significant. What would be the maximum theoretical percent recovery (first crop only) from the crystallization of 5.0 g of acetanilide from 100
  mL of water (assuming the solution is chilled to 0)?

All 5 g of acetanilide would go into the hot water. On cooling, 0.53 g would remain in solution.
Therefore, 5 g  0.53 g = 4.57 g. The maximum percent recovery is 4.57 g/5 g = 0.91, or 91.
