Equivalent Weight Solution

STEP 0: Pre-Calculation Summary

Formula Used

Equivalent Weight = Molecular Weight/N Factor
W _eq = MW/nf
This formula uses 3 Variables

Variables Used

Equivalent Weight - (Measured in Kilogram) - Equivalent Weight (also known as gram equivalent) is the mass of one equivalent, that is the mass of a given substance.
Molecular Weight - (Measured in Kilogram) - Molecular Weight is the mass of a given molecule.
N Factor - N Factor of substance in a redox reaction is equal to the number of moles of electron lost or gained per mole.

STEP 1: Convert Input(s) to Base Unit

Molecular Weight: 120 Gram --> 0.12 Kilogram (Check conversion here)
N Factor: 9 --> No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

W _eq = MW/nf --> 0.12/9

Evaluating ... ...

W _eq = 0.0133333333333333

STEP 3: Convert Result to Output's Unit

0.0133333333333333 Kilogram -->13.3333333333333 Gram (Check conversion here)

FINAL ANSWER

13.3333333333333 ≈ 13.33333 Gram <-- Equivalent Weight
