The solubility of acetanilide in your recrystallizing solvent is 5.0 mg per mL at 10 degrees Celsius. Calculate the maximum percent recovery in this experiment, assuming a 15.0 mL recrystallizing solution is filtered at 10 degrees Celsius.

Answer 1

You didn't post all of the problem. The LOSS using 15.0 mL will be
5 mg/mL x 15.0 mL = 75 mg. So percent recovery will be
[(yield-75 mg)/yield]*100 = ?

Answer 2

15%
