# Molarity Calculator

> Find molarity, moles, volume, or mass from any three known values using M = n / V (and n = m / M when molar mass is supplied). Educational chemistry only, not lab or dosing advice.

## Quick Answer

Calculate molarity, moles, volume, or mass of a solution. Enter any three known values to find the remaining variable.

## Definition

Molarity, or molar concentration, is a measure of the concentration of a solute in a solution, defined as the number of moles of solute dissolved per liter of solution. A molarity calculator computes molarity, solute moles, or solution volume based on the formula M = n / V. When the solute's molar mass is provided, the tool also computes solute mass from the relationship n = m / M. Chemists and students use this calculation to prepare solutions of specific concentrations and to perform stoichiometric analysis in chemical reactions.

## How to Use

1. **Select parameter to calculate** — Choose the target variable you want to solve for, such as molarity, moles, volume, or mass.
2. **Input known values** — Enter the values for the other three variables in their respective units.
3. **Enter molar mass (optional)** — Provide the molar mass of the solute in grams per mole if you need to calculate mass.
4. **Read the result** — View the calculated value along with the mathematical formula and step-by-step working.
