(a) Cholesterol isolated from natural sources is enantiopure. The observed rotation of a 0.3-g sample of cholesterol in 15 mL of chloroform solution contained in a 10-cm polarimeter tube is −0.78°. Calculate the specific rotation of cholesterol.
(b) A sample of synthetic cholesterol consisting entirely of (+)-cholesterol was mixed with some natural (−)-cholesterol. The specific rotation of the mixture was −13°. What fraction of the mixture was (+)-cholesterol?
