%ee = (abs(R-S)/(R+S))*100
This formula uses 1 Functions, 3 Variables
Functions Used
abs - Absolut value function, abs(Number)
Variables Used
Percent Enantiomeric Excess - Percent Enantiomeric Excess is a measurement of purity used for chiral substances. It reflects the percent to which a sample contains one enantiomer in greater amounts than the other.
Moles of R - (Measured in Mole) - Moles of R is the unit of measurement for amount of substance, a quantity proportional to the number of elementary entities of a substance.
Moles of S - (Measured in Mole) - Moles of S is the unit of measurement for amount of substance, a quantity proportional to the number of elementary entities of a substance.
STEP 1: Convert Input(s) to Base Unit
Moles of R: 12.8 Mole --> 12.8 Mole No Conversion Required
Moles of S: 5.6 Mole --> 5.6 Mole No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
%ee = (abs(R-S)/(R+S))*100 --> (abs(12.8-5.6)/(12.8+5.6))*100
Evaluating ... ...
%ee = 39.1304347826087
STEP 3: Convert Result to Output's Unit
39.1304347826087 --> No Conversion Required
39.1304347826087 39.13043 <-- Percent Enantiomeric Excess

## 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.
