the ether-water pair of Kdist

At room temperature a substance has a distribution constant for the ether-water pair ofKdist = [S]organic/[S]aqueous = 1.7. Suppose you had 150 mL of a water solution of this material at a concentration of 2.4 g/L.(a) To the nearest mL what volume of ether would be required to extract 50% of the material?(b) If the extraction were repeated with the same volume of ether as in part (a) how much more would be extracted?
