The distribution coefficient between methylene chloride and water for solute Y is 9. An amount of 125.0.0 g of Y is dissolved in 160 mL of water.
a) What weight of Y would be removed from water with a single extraction with 160-mL of methylene chloride? Report to 1 decimal place.
b) What weight of Y would be removed from water (the original solution with the original amount) with two successive extractions with 80-mL portions each of methylene chloride? Report to 1 decimal place.

Suppose solute A has a distribution coefficient of 1.0 between water and diethyl ether. Demonstrate that if 4.0 mL of a solution of 0.20 g of A in water were extracted with two 1.0-mL portions of ether, a smaller amount of A would remain in the water that if the solution were extracted with one 2.0-mL portion of ether.
