About this tool
Find the final volume and how much solvent to add to dilute a solution.
C₁·V₁ = C₂·V₂, so V₂ = C₁·V₁ ÷ C₂. Solvent to add = V₂ − V₁.
Formula: V₂ = C₁V₁/C₂
Example: Starting concentration (C₁) = 2, Starting volume (V₁) = 50, Target concentration (C₂) = 0.5 → Final volume (V₂) = 200, Solvent to add = 150.
Use the same units for both concentrations and both volumes.

FAQ
How does the Dilution Calculator (C₁V₁ = C₂V₂) work?
C₁·V₁ = C₂·V₂, so V₂ = C₁·V₁ ÷ C₂. Solvent to add = V₂ − V₁.
What should I keep in mind?
Use the same units for both concentrations and both volumes.
