A has a partition coefficient of 3 between toluene and water, with three times as much in the toluene phase. Suppose that 100 mL of a 0.010 M aqueous solution of A is extractedmwith toluene. You have 100 mL of toluene total and need the extraction to be 90% complete (only 10% remains in aqueous phase). Describe how this can be done.
