Compound Z has a solubility limit of 32.5 g/L in diethyl ether. Compund Z has a solubility limit od 2.5 g/L in water. You are given a 100 mL aqueous solution that contains 200 mL of compund Z. If you do three 33.3 mL extractions of Z using diethyl ether:
1) what is the K value for compound Z in the biphasic system
2) how much do you remove in each individual extraction
3) how much of compoun Z is extracted with each of those 33.3 mL extractions added together
4) how much is still in the water layer at the end of all three extractions?
