Dilution Calculator: C1V1 = C2V2 in Practice
Dilution keeps the amount of solute and adds solvent. One equation tracks that balance from stock to target concentration.
What is the Dilution Calculator?
Enter the starting concentration and volume plus the target concentration. The tool solves C1V1 = C2V2 for the final volume. It assumes volumes add simply and the solute amount stays the same.
How to use it
- Enter starting concentration and volume.
- Enter the target concentration.
- Click Calculate Dilution.
Worked example
Diluting 50 mL of 2 mol/L to 0.5 mol/L gives a final volume of 200 mL, so 150 mL of solvent is added.
How do you dilute 50 mL of 2 mol/L to 0.5 mol/L?
To 200 mL final volume, adding 150 mL of solvent, by C1V1 = C2V2.
Frequently asked questions
Does solvent to add equal final minus initial?
Yes, on the usual assumption that volumes add simply.
Can I use any concentration units?
Yes, as long as both concentrations use the same units.
