Solution Dilution Calculator
The dilution tool applies solute conservation to estimate final concentration after increasing solution volume.
How to use this calculator
- Enter initial concentration, initial volume and final volume in matching units. Final volume must be at least the initial volume.
- Check the labels and units before using a result outside this page.
- Change one input at a time if you want to compare scenarios.
Formula and method
C₁V₁ = C₂V₂; therefore C₂ = C₁V₁ ÷ V₂
- C₁V₁ = C₂V₂; therefore C₂ = C₁V₁ ÷ V₂
- Volumes must be compatible and the solute amount must remain conserved; real mixing volumes may not be perfectly additive.
Worked examples
Worked example
Dilute 100 mL of a 2 mol/L solution to a final volume of 500 mL.
Final concentration = 2 × 100/500 = 0.4 mol/L.
Final concentration = 2 × 100/500 = 0.4 mol/L.
