Suppose a compound Z had a partition coefficient of 8.0 in ether-water. If 10.0 g of Z was dissolved in 100 mL of water, and if the water solution was extracted with two 100 mL portions of ether, answer the following questions. show your calculation.
a) What is the total amount of Z contained in the 200 mL of ether extract after the two extractions?
b) Instead of using two 100ml portions of ether. a single extraction had been carried out using one 200 mL portion of ether. What weight of Z would be contained in the ether solution under these conditions?
