Solute A has a distribution coefficient of 9.0 between methylene chloride and water. Show that extracting a solution containing 1.0 mole of A in 100. mL of water is more efficient if two 25 extractions with methylene chloride are performed rather than a single 50. mL extraction with methylene chloride.
