Percent Enantiomeric Excess Considering Amount of Enantiomer

Go Percent Enantiomeric Excess = (abs(Moles of R-Moles of S)/(Moles of R+Moles of S))*100

Specific Rotation of Optically Active Compound

Go Specific Rotation = Observed Rotation/(Length Of Sample Tube*Concentration of Solution in Polarimeter)

Percent Enantiomeric Excess

Go Percent Enantiomeric Excess = abs(Mole Fraction of R-Mole Fraction of S)*100

Enantiomeric Excess

Go Enantiomeric Excess = abs(Mole Fraction of R-Mole Fraction of S)

Optical Purity

Go Optical Purity = (Observed Specific Rotation/Maximum Specific Rotation)*100

Fraction of Major Isomer

Go Mole Fraction of R = 50+(Percent Enantiomeric Excess/2)

Fraction of Minor Isomer

Go Mole Fraction of S = 50-(Percent Enantiomeric Excess/2)

Fraction of Major Isomer Formula

Mole Fraction of R = 50+(Percent Enantiomeric Excess/2)
F_R = 50+(%ee/2)

What are R and S?

To name the enantiomers of a compound unambiguously, their names must include the "handedness" of the molecule. The method for this is formally known as R/S nomenclature. The letters "R" and "S" are determined by applying the Cahn-Ingold-Prelog (CIP) rules. The optical activity (+/-) can also be communicated in the name, but must be empirically derived.
