Specific Rotation Calculation in Optical Activity

SOLVED: The specific optical rotation of the pure enantiomer (S)-(-)-mandelic acid is -116 degrees. It is so interested in isolating the S enantiomer, the reaction mixture has a specific optical rotation of -107 degrees. Present the calculations.a) Calculate the enantiomeric excess.b) How much percent is it of a racemic mixture?c) How much percent in total does it have of the S enantiomer in total?2. Correctedtext: A solution is prepared by dissolving 500 mg of testosterone in 20 mL of ethanol.
