Asked by A Giles
The solubility of acetanilide is 3.53 g in 100 mL of chloroform at 0 °C, and 29.1 g in 100 mL of chloroform at 60 °C. What is the maximum percent recovery that can be achieved for the recrystallization of acetanilide from chloroform?
Hint: During a recrystallization, some of the acetanilide stays in solution. The percent recovery expresses the ratio of pure material to crude starting material as a percentage.

You can make the problem easier by choosing to dissolve 29.1 g acetanilide in 100 mL solvent at 60 C.
Then you cool it to O c and it will dissolve 3.53g. How much do you recover?
That's 29.1-3.53 = ? grams recovered.
What percent is that?
That's (?g/29.1)*100 = ?%
