Caffeine has an octanol-water partition coefficient, or Kow, of 0.616. A cup (237 mL) of coffee contains 95 mg of caffeine. If you want to extract caffeine from a cup of coffee using liquid-liquid extraction (LLE) with a separatory funnel and ethyl acetate as the solvent, how many extractions and how much solvent will be used to extract 92 mg of caffeine, if 237 mL each of coffee and ethyl acetate are used in each extraction?
