Question
Tea leaves were boiled in water and around 1.50 grams of caffeine were extracted by 200.0 mL of water. If three portions of 25.0 mL of dichloromethane were used to extract the caffeine from the aqueous layer, how much caffeine will be extracted by the dichloromethane?
Solubility of caffeine in water: 2.18 g per 100 mL water
Solubility of caffeine in dichloromethane: 18.2 g per 100 mL dichloromethane
