3. The solubility of benzoic acid at 25 degrees Celsius in water and diethyl ether is 3.35 mg/mL and 0.353 g/mL, respectively. Estimate the percent recovery of benzoic acid in the organic phase, if a solution of benzoic acid in water is extracted with an equivalent volume of ether. [HINT-pay attention to the units]
4. The solubilities of cholesterol in water and chloroform are 0.550mg/100mL and 1.00g/5.25mL, respectively. Estimate the partition coefficient of cholesterol between chloroform and water. [HINT- units] What conclusion can be drawn about the polarity of cholesterol?
