## Use
Open the calculator page and enter values. Query-string parameters can restore and bookmark a calculation.
Example: https://askcalculators.com/calculator/molarity-calculator/?mass=58.44&volume=1&molWeight=58.44

## Inputs
- mass: Mass of Solute (g); type=number; optional; default=58.44
- volume: Volume of Solution (L); type=number; optional; default=1
- molWeight: Molecular Weight (g/mol); type=number; optional; default=58.44

## Outputs
- result: Result; format=text; primary

## Formula
Molarity = moles of solute ÷ solution volume in liters.

## Rules
- Empty optional inputs are undefined, not zero.
- Hidden conditional inputs are ignored.
- Do not invent missing required inputs.
