Formula and methodology
Formula: Molarity = (percent w/v × 10 g/L) / molar mass (g/mol).
A percent w/v value states grams of solute per 100 mL of final solution. Multiplying by ten converts it to grams per liter; dividing by molar mass then converts grams per liter into moles per liter.
This result follows the calculator's declared inputs, precision, validation boundaries, and model limits.
Input contract
- Percent w/v — g/100 mL; minimum 0; maximum 1000000000
- Solute molar mass — g/mol; minimum 1.0E-6; maximum 1000000
Worked example
| Input | Value |
|---|---|
| Percent w/v | 5 |
| Solute molar mass | 58.44 |
0.8556 M
Assumptions and limits
- The percentage is w/v, not w/w or v/v, and describes final solution volume.
- Molar mass is in grams per mole for the same solute formula.
- The conversion does not account for dissociation, activity, density, purity, or temperature.
