Dilution Calculator
Calculate final concentration after dilution
About this calculator
A dilution calculator is an essential tool for scientists, researchers, and students who need to prepare solutions with specific concentrations. It uses the dilution formula C1V1 = C2V2 to calculate the final concentration when a stock solution is diluted with solvent. This calculator is particularly useful in laboratory work, pharmaceutical preparations, and educational settings where accurate dilutions are critical for experimental success and safety protocols.
How to use
Enter your initial concentration (C1) and initial volume (V1) of the stock solution. Then input either the final volume (V2) or desired final concentration (C2). The calculator will automatically compute the missing value using the dilution equation, showing you the exact concentration or volume needed for your diluted solution.
Frequently asked questions
What is the dilution formula used in this calculator?
The calculator uses C1V1 = C2V2, where C1 is initial concentration, V1 is initial volume, C2 is final concentration, and V2 is final volume.
Can I use different units for concentration and volume?
Yes, you can use any units as long as they're consistent. Common units include molarity, percentage, ppm for concentration and mL, L for volume.
What's the difference between dilution and concentration?
Dilution decreases concentration by adding solvent, while concentration increases by removing solvent. This calculator specifically handles dilution calculations where final concentration is lower than initial.
