A solution is prepared by mixing 5 mL of a 0.20 M solution of the S enantiomer of a compound and 10 mL of a 0.20 M solution of the R enantiomer. The specific rotation of that solution was -7.00.
a.) Calculate the millimoles of each enantiomer in the mixture.
b.) Calculate the% enantiomer in excess (% e.e).
c.) Calculate the specific rotation of each pure enantiomer.
Expert Solution
Step 1
Given: Concentration of S enantiomer = 0.20 M
Volume of S enantiomer solution = 5 mL
Concentration of R enantiomer = 0.20 M
Volume of R enantiomer solution = 10 mL
And the specific rotation of the solution = -7.00o.
