The partition coefficient of benzoic acid is three in dichloromethane (a.k.a. methylene chloride) with respect to water.
1. If 6 grams of benzoic acid were dissolved in 600mL of water, explain how much benzoic acid would be extracted with four150-mL portions of dichloromethane
2. After four extractions, explain what percentage of the benzoic acid has been extracted use percent recovery?
