The distribution coefficient, KD (ether/water), between ether and water for aspirin at room temperature is 3.5. What weight of aspirin would be extracted by a single extraction with 60 ml of water from a solution of 10 grams of aspirin in 100 ml of ether? Calculate the weight of aspirin which would be removed by three extractions with 20 ml portions of water.
