Dilution Calculator
Solve C1V1=C2V2 for any dilution quantity.
About this tool
The dilution equation C\u2081V\u2081 = C\u2082V\u2082 relates a solution's concentration and volume before and after dilution. Pick which quantity you need and enter the other three.

Frequently Asked Questions
Use consistent units for concentration (both C\u2081 and C\u2082 in the same unit, like mol/L or %) and consistent units for volume (both V\u2081 and V\u2082 in the same unit, like mL or L) \u2014 the equation works with any units as long as each pair matches.
Initial (1) is your starting stock solution before dilution; final (2) is the solution after you've added solvent to dilute it. V\u2082 is always the total volume after dilution, not just the solvent added.
