    1. A solution of 0.5g (-)-epinephrine dissolved in 10mL of dilute HCl was placed in a 20-cm polarimeter tube. Its optical rotation in sodium line (light wavelenth) was -5.0 degrees at 25 degrees Celsius. What is the specific rotation of the (-)-epinephrine?

    2. Calculate the enantiomeric excess (e.e.), a measure of optical purity of a substance, and the specific rotation of a mixture containing 6g of (+)-2-butanol and 4g of (-)-2-butanol.
