Formula
N = M x n-factor Symbol legend
| Symbol | Meaning | Unit | Copy |
|---|---|---|---|
N | Normality | eq/L | |
M | Molarity | mol/L | |
n | Equivalent factor | equivalents/mol |
- Enter molarity M of your solution.
- Enter n-factor based on reaction context.
- Multiply to obtain normality N.
Example
Worked example: 0.50 M with n = 2
- 1 M = 0.50 mol/L
- 2 n = 2
- 3 N = M x n = 0.50 x 2 = 1.00
Normality is 1.00 N.
How
- Enter molarity value in mol/L.
- Enter equivalent factor n.
- Read resulting normality in eq/L.
Avoid
- Using the wrong n-factor for the specific reaction.
- Assuming normality equals molarity in all cases.
- Applying acid-base n-factor to unrelated redox calculations.
Checks
Best fit
Normality Calculator is built for convert molarity to normality using equivalent factor for acid-base and redox style concentration calculations. If Normality Calculator does not match the input scope, compare the answer with a second method.
Input check
Check N before calculating: it means normality and is measured in eq/L.
Sanity check
For Normality Calculator, use the worked example as a quick benchmark: Normality is 1.00 N. If the normality calculator answer is far away, check whether an input, unit, or mode changed.
Before copying
Review this common issue first: using the wrong n-factor for the specific reaction.
Ref only. Verify values. Follow lab safety.
FAQ
Is normality always the same as molarity?
No. They are equal only when n-factor is 1.
How do I choose n-factor?
Choose n based on reaction equivalents, such as protons transferred or electrons exchanged.
Can I use decimal n-factor?
Yes, if your equivalent relationship requires it.
