Calculators for every common way of expressing concentration: molarity, molality, mass percent, ppm and mole fraction, plus the dilution equation and colligative properties of water solutions.

Calculate the molarity of a solution from the mass of solute, its molar mass and the volume, or find the mass needed to make a solution of a given molarity.

Dilution (C₁V₁ = C₂V₂)

Use the dilution equation C₁V₁ = C₂V₂ to find the volume of stock solution needed, the final concentration or the final volume, and how much solvent to add.

Calculate molality (mol per kg of solvent) from the mass of solute, its molar mass and the mass of solvent, plus the freezing point depression and boiling point elevation in water.

Calculate the concentration of a solution as mass percent (w/w), mass fraction, parts per million (ppm) and parts per billion from the mass of solute and solvent.

Calculate the mole fraction of each component in a two-component mixture from their masses and molar masses, plus their mole percentages.
