Percent Enantiomeric Excess Considering Amount of Enantiomer Solution

STEP 0: Pre-Calculation Summary

Formula Used

Percent Enantiomeric Excess = (abs(Moles of R-Moles of S)/(Moles of R+Moles of S))*100
%ee = (abs(R-S)/(R+S))*100
This formula uses 1 Functions, 3 Variables

Functions Used

abs - The absolute value of a number is its distance from zero on the number line. It's always a positive value, as it represents the magnitude of a number without considering its direction., 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

FINAL ANSWER

39.1304347826087 ≈ 39.13043 <-- Percent Enantiomeric Excess

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

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.
