1) While working in the lab, 10 g of compound X was accidently dissolved in 100 mL of water. In order to recover compound X, the aqueous solution was extracted with 20 mL of dichloromethane. After concentrating the organic phase, it was found that 7 g of compound X was recovered.

a.      Calculate the partition coefficient of compound X between dichloromethane and water. (show your work for full credit)

b.      After a second extraction of the aqueous portion with 20 mL of dichloromethane will the total recovery of compound X be 100%? (Yes or No)
