Hi,
I dont know if I have posted this question in the correct forum. It is based on organic, but is also high school chemistry.

A sample of synthetic camphor contains both 'd' and 'l' isomers in unequal amounts. The specific rotation of the sample is -13.9^.. What is the enantiomeric excess of the sample?

Can you please tell me how to do this problem? thanks.
