The question reads: The optical rotation of pure pencicillin G is +206 degrees. A sample of pencillin G was found to have an optical rotation of +103 degrees. Calculate the enantiomeric excess (ee) in the mixture.
I did so by: 103/203 x 100 = 50%
Here is where I am lost:
Next calculate the precent composition of the (+) enantiomer.
What the heck is that? I know it is a mole fraction but how do I know what to plug in. Any ideas?
