What is the Dilution Calculator?
When you dilute a solution, the amount of solute stays the same: C₁ × V₁ = C₂ × V₂. Choose which value you want to find, enter the other three (use the same units on both sides) and the calculator tells you the answer plus exactly how much water/solvent to add.
How to use the Dilution Calculator
- Choose the unknown (V₁, C₂, V₂ or C₁).
- Enter the three known values with matching units.
- Follow the mixing instruction shown.
Example
To make 500 mL of 0.1 M from a 2 M stock: V₁ = 0.1 × 500 ÷ 2 = 25 mL of stock + 475 mL water.
This Dilution Calculator is 100% free, needs no signup and runs privately in your browser – on phone, tablet or computer.
