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)

Equivalent Weight Formula

Equivalent Weight = Molecular Weight/N Factor
W eq = MW/nf

What is n factor?

N Factor of substance in redox reaction is equal to number of moles of electron lost or gained per mole. n-fact of substance in non-redox reaction is equal to the product of displaced mole and its charge.

How to Calculate Equivalent Weight?

Equivalent Weight calculator uses Equivalent Weight = Molecular Weight/N Factor to calculate the Equivalent Weight, Equivalent Weight is the mass of one equivalent, that is the mass of a given substance which will combine with or displace a fixed quantity of another substance. Equivalent Weight is denoted by W eq symbol.

How to calculate Equivalent Weight using this online calculator? To use this online calculator for Equivalent Weight, enter Molecular Weight (MW) & N Factor (nf) and hit the calculate button. Here is how the Equivalent Weight calculation can be explained with given input values -> 13333.33 = 0.12/9.

FAQ

What is Equivalent Weight?
