C1V1 = C2V2 Calculator
What is the C1V1 = C2V2 Formula?
The C1V1 = C2V2 formula is a fundamental equation in chemistry used to calculate dilutions.
C1: Initial concentration of the stock solution.
V1: Volume of the stock solution you have.
C2: Desired final concentration.
V2: Final volume required to achieve C2.
Mathematically, it is expressed as:

C1×V1=C2×V2
This formula allows chemists and lab technicians to calculate exactly how much of a concentrated solution to dilute to reach a specific concentration.
How to Use the C1V1 = C2V2 Calculator
Our tool eliminates manual calculations. Here’s how to use it step by step:
Enter Initial Concentration (C1): Input the concentration of your stock solution.
Enter Initial Volume (V1): Provide the volume you currently have.
Enter Desired Final Concentration (C2): Specify the concentration you need for your experiment.
Click “Calculate V2”: The calculator instantly displays V2, the volume of solution required to reach C2.
Reset if Needed: Click “Reset” to clear all inputs and start over.
The tool also ensures input validation; it only accepts positive numbers, avoiding errors in calculations.
Example of Using the C1V1 = C2V2 Calculator
Scenario:
You have 50 mL of a 2 M stock solution (C1 = 2 M, V1 = 50 mL) and need a 0.5 M solution (C2 = 0.5 M).
Step 1: Input C1 = 2
Step 2: Input V1 = 50
Step 3: Input C2 = 0.5
Step 4: Click Calculate V2
Result:
