Multiplier (n) vs Empirical Formula Mass
How to Find the Molecular Formula
Formula
n = actual molar mass / empirical formula mass
Multiply all subscripts in the empirical formula by n to get the molecular formula.
Example Calculation
Empirical formula CH2O (30.03 g/mol), actual molar mass 180.16 g/mol.
- 01n = 180.16 / 30.03
- 02n = 6
- 03Molecular formula = C6H12O6 (glucose)
