Dilution Calculator

Calculate dilution parameters using M₁V₁ = M₂V₂ formula

M₁V₁ = M₂V₂

Dilution Formula (Initial Molarity × Initial Volume = Final Molarity × Final Volume)

Calculation Mode

Calculate the volume of stock solution needed

Input

Initial Molarity (M₁)

Final Molarity (M₂)

Final Volume (V₂)

Volume Unit

How to use Dilution Calculator

1Enter the starting concentration and volume, and either the target concentration or target volume.
2Let the tool compute the missing value using the dilution relationship.
3Read how much solvent to add or what final volume to reach.

C1 x V1 = C2 x V2

Dilution keeps the amount of solute constant while adding solvent, so the product of concentration and volume stays equal before and after.

It is the backbone of preparing standards and dosing liquids; always add solvent to reach the final volume, not just mix equal parts.

What does C1V1 = C2V2 mean?

The moles of solute before equal the moles after; concentration drops as volume rises.

Do units need to match?

Concentration units must match on both sides, and volume units must match; the ratio is what matters.

Can I dilute to any concentration?

Yes mathematically, but practical limits include measurement precision and solubility.
