When performing extractions it is often better to do multiple extractions rather than one large volume extraction. suppose you have 100mg of a sample dissolved in 0.6ml of water. the partition coefficient or kp for this compound in water and diethyl ether is 4.0

a. calculate how much total compound you would obtain with 3 x 0.2ml extractions with ether

b. calculate how much you would obtain with 1 x 0.6ml extraction

c. which method is more efficient?
