Consider a 0.3 L aqueous solution that contains 2.6 g ofcaffeine. The solubility of caffeine in water is 2.2 g/100 mL andthe solubility in methylene chloride is 10.2 g/100 mL.
a) How much caffeine can be extracted with 70 mL of methylenechloride?
b) How much caffeine will be extracted if the aqueous solutionis extracted twice with 30 mL of methylene chloride?
c) Which is more effective a or b?
