A student is using the polarimeter to analyze a solution containing a mixture of enantiomers. The student observes a rotation of -32.8º. Knowing the cell length is 10.5 cm, the concentration of the solution is 0.79 g/mL, and the specific rotation of the pure (-)-enantiomer is -53.6º, what is the percent enantiomeric excess of the (-)-enantiomer in the student's solution?
