How It Works
How to Calculate Equivalent Weight
Formula
Equivalent weight = Molar mass / n-factor
The n-factor depends on the reaction type (acid-base, redox, etc.).
Worked Example
H2SO4 (98.08 g/mol) as a diprotic acid (n=2).
molar_mass = 98.08n_factor = 2
- 01Eq. weight = 98.08 / 2
- 02Eq. weight = 49.04 g/equiv
