The distribution coefficient, k = concentration in hexanes + concentration in water, between hexanes and water for solute A is 7.5. What weight of A would be removed from a solution of 10 g of A in 100 mL of water by a single extrac- tion with 100 mL of hexanes? What weight of A would be removed by four successive extractions with 25-mL portions of hexanes? How much hexanes would be required to remove 98.5% of A in a single extraction?
