Molarity Calculator accuracy and testing

This page documents how Calwarden builds trust for this calculator: source notes, regression-style default tests, limitations, assumptions, unit handling, rounding, and visible change history.

Formula source

**Formula:** 1. **Moles (n)** = Mass (g) / Molecular Weight (g/mol) 2. **Molarity (M)** = Moles (n) / Volume (L)

Test cases

Default input regression check

Generated from the checked-in default inputs and calculate function.

Inputs

Mass of Solute: 58.44 g
Molecular Weight: 58.44 g/mol
Volume of Solution: 1 L

Expected outputs

Molarity: 1 M (mol/L)
Moles: 1 mol

Known limitations

This page documents the checked-in calculator logic and does not certify results for every real-world edge case.
Use the result as a planning estimate unless the calculator page states a stricter purpose.

Assumptions

Mass, molar mass, and final solution volume are finite numeric inputs.
Molar mass and solution volume must be greater than zero.
The calculation assumes the entered volume is the final solution volume, not just the solvent added.

Unit handling

Mass of Solute accepts values in g.
Molecular Weight accepts values in g/mol.
Volume of Solution accepts values in L.
Molarity is displayed in M (mol/L).
Moles is displayed in mol.

Rounding rules

Number displays use up to 2 decimal places in the calculator UI.
