Suppose solute A has a distribution coefficient of 1.0 between water and diethyl ether. Demonstrate that of 100mL of a solution of 5.0g of A in water were extracted with two 25-mL portions of ether, a smaller amount of A would remain in the water than if the solution were extracted with one 20-mL portion of ether

Kd=co/ca
1=( x/25 ml)/(5-x)/100ml
X=1
5-x = 4
