It is important to always minimize the amount of solvent used, allowing for evaporation. If we add a relatively large excess, we expect our recrystallization to produce lower percent recoveries. A common mistake is to misplace the decimal, resulting in addition of 11x the solvent instead of the recommended 1.1x. If a substance dissolves in a solvent at 1g/463 mL at room temperature and at 1g/12 mL at the solvent's boiling point, what would be the maximum expected amount recovered if using 11x the minimum amount of solvent in recrystallizing 10 g of the substance?
