Organic Chemistry, enantiomeric excess and specific rotation questions, very short two questions

March 15, 2023March 15, 2023 Discipline: Chemistry
Learning Goal: I’m working on a chemistry question and need the explanation and answer to help me learn.

1. The specific rotation of pure (+)-camphor is +44 degrees. A sample containing this compound and its enantiomer in some combination was found to have a specific rotation of 27 degrees. What is the fraction (in decimal form, 0 < x < 1) of (+)-camphor in the mixture

2. The specific rotation of a pure chiral (+) molecule is 15º. What is the specific rotation (in degrees) of a solution that is 81% of the (+) enantiomer? Best to do the calculation to at least 3 significant figures but then please report your answer to 2 significant figures.

Requirements: just the answer
