Molarity Calculator

Free Online Molarity Calculator to compute solute concentrations (mol/L) and perform dilution calculations quickly. Ideal for chemistry students, labs, and research.

Input

Molarity (M) = moles of solute / liters of solution

Mass of Solute (g)

Molar Mass of Solute (g/mol)

Volume of Solution

Volume Unit

Output

Enter the amount of solute and the volume of solution to calculate molarity instantly!

Calcify's Molarity Calculator will help you find the molar concentration of a solution — the moles of solute divided by the number of liters of solution. This is useful in chemistry labs, pharmacy prep, biology lab work, and anywhere academic work requires precise concentration of solutions. You can enter volume, solute amount, or desired molarity, and the tool gives you the missing value.

For example, if you need to prepare 1 liter of a 0.5 M solution, the Molarity Calculator can tell you how many moles (and therefore grams, once you know molar mass) of the compound you need to add. That reduces trial and error when mixing solutions. Use the Molarity Calculator to plan clean, repeatable lab work, and then explore more science and math tools on Calcify.

FAQs

A Molarity Calculator is a tool used to find how concentrated a solution is (in moles/L) of solute(s).

Enter solute amount, molar mass, and solution volume; the Molarity Calculator online tool will provide the molarity instantly.

Yes, the molarity dilution calculator section helps you adjust solution concentrations accurately.

M = moles of solute / volume of solution (L), as well M1 × V1 = M2 × V2, when diluting a solution.
