(+)-menthol has a specific rotation of +50°. A mixture of (+)-menthol and (-)-menthol in a certain synthetic sample was analyzed as follows. 6.972 g of sample was dissolved to make a 25 mL solution, and then placed in a 10 cm tube. The optical rotation of the solution was -10⁰. What is the enantiomeric excess of the mixture? Report your answer to the correct number of significant figures. % ee Which enantiomer (+ or -) corresponds to the major enantiomer present? )-menthol What are the percentages of each enantiomer in the mixture? Report your answer to the correct number of significant figures. % (+)-menthol % (-)-menthol
