What this calculator does
Normality of a solution works out converts molarity to normality using the number of equivalents per mole. Enter your own figures above and the answer updates as you type: nothing is fixed in the code, so the result reflects exactly the numbers you supply.
The formula this calculator evaluates is printed under the tool and explained below, so you can check the working by hand or reuse it in a spreadsheet.
The formula
FormulaN = M × n, where M is molarity (mol/L) and n is the number of equivalents (valency factor) per mole of solute
The inputs explained
| Field | What to enter |
|---|---|
| Molarity (mol/L) | A number, measured in mol/L. Starts at 1. |
| Equivalents per mole (n-factor) | A number. Starts at 2. |
Worked examples
Every figure in the tables below is produced by this page’s own calculator at build time, so the numbers and the tool always agree. Select any row to load that scenario.
How the answer changes with molarity
Every other input is held at the calculator’s starting values while molarity varies. Select any row to load that scenario into the calculator.
