Dilution Calculator
Calculate required final volume for a dilution using C1V1=C2V2.
How to use
- Enter initial concentration C1 and initial volume V1.
- Enter target concentration C2 to solve for final volume V2.
Capabilities and scope
The calculation assumes the amount of solute is conserved during dilution.
How it works
It uses V2 = C1×V1/C2.
Example
100 mL of 1 M stock diluted to 0.2 M requires final volume 500 mL.
Useful for
- Plan a stock-solution dilution
- Verify C1V1=C2V2 calculations
Before you use it
- It ignores reaction, contraction, and unit mismatch, and target concentration cannot be zero.
Frequently asked questions
How much solvent should I add?
Under the ideal-volume assumption, subtract V1 from the calculated V2.
