What is the ee for each of the following mixtures of enantiomers A and B?
85% A and 15% B
The enantiomeric excess explains the excess of one enantiomer over another in a given mixture. Thus, from the enantiomeric excess, the presence of amount of pure sample in a given mixture can be obtained, and thus purity of the given sample can be determined.
