Molarity Calculator for Chemistry Solutions

Molarity (M) is a measure of the concentration of a chemical solution, expressed as moles of solute per liter of solution. A molarity calculator is essential in chemistry labs for preparing solutions of precise concentrations for experiments, titrations, and pharmaceutical applications.

Common Uses

Preparing laboratory solutions of known concentration
Titration calculations
Pharmaceutical drug concentration calculations
Dilution calculations (C1V1 = C2V2)

Frequently Asked Questions

How is molarity calculated?

Molarity (M) = Moles of solute ÷ Liters of solution. To find moles from mass: Moles = Mass (g) ÷ Molar Mass (g/mol). Example: Dissolving 58.44 g of NaCl (molar mass 58.44 g/mol) in 1 liter of water gives a 1 M NaCl solution.

What is the dilution formula?

C1 × V1 = C2 × V2, where C = concentration (molarity) and V = volume. To dilute a 10 M solution to 1 M with a final volume of 1 liter: V1 = (1 M × 1 L) ÷ 10 M = 0.1 L. Take 100 mL of the 10 M solution and add water to reach 1 liter.
