Assume that the partition coefficient, K, for partitioning of compound A between diethyl ether and water is 3; that is, A preferentially partitions into ether.
a.) Given 400 mL of an aqueous solution containing 12 g of compound A, how many grams of A could be removed from the solution by a single extraction with 200 mL of diethyl ether?
b.) How many total grams of A can be removed from the aqueous solution with three successive extractions of 67 mL each?
