What is the formula for calculating solution molarity?
Molarity (M) is calculated by dividing the total number of moles of solute by the absolute volume of the solution in liters: M = mol / L. One mole equals the substance's molecular weight in grams.
Inputs and Formula Variables
Solute mass (g)
The measured mass of dissolved chemical used to compute moles of solute.
Molar mass of solute (g/mol)
The compound molecular weight that converts laboratory grams into mole yield.
Total solution volume (L or mL)
The final absolute solution volume converted to liters for concentration calculation.
Molarity workflow for solution prep
The calculator first converts grams of solute to moles, then divides by final solution volume in liters. Unit dropdowns keep the formula consistent while supporting lab-style concentrations.
The yield value shown here is mole yield from the measured solute mass, which helps technicians verify whether the prepared amount matches the intended solution concentration.
- Use liters for the denominator even when volume is entered in milliliters.
- mM, uM, and nM outputs are scaled versions of the same molar concentration.
- Keep significant figures aligned with the least precise measured input.
