- Final Volume (V₂)
Steps
- Select the Find C₂ tab.
- Enter the initial concentration (C₁).
- Enter the initial volume (V₁).
- Enter the final volume (V₂).
- Click Calculate.
- The calculator instantly displays the final concentration (C₂).
Method 3: Find Initial Concentration (C₁)
Use this option when you know:
- Final Concentration (C₂)
- Final Volume (V₂)
- Initial Volume (V₁)
Steps
- Select the Find C₁ tab.
- Enter the final concentration (C₂).

Practical Example 1: Preparing a Laboratory Solution
Suppose a researcher has:
- Initial concentration = 100 mg/mL
- Initial volume = 10 mL
- Desired concentration = 20 mg/mL
Using the calculator:
V₂ = (100 × 10) ÷ 20
Result:
- Final Volume = 50 mL
- Diluent Needed = 40 mL
This means the researcher must add 40 mL of diluent to achieve the desired concentration.
Practical Example 2: Educational Chemistry Experiment
A student has:
- Initial concentration = 2 M
- Initial volume = 25 mL
- Final volume = 100 mL
Using the calculator:
C₂ = (2 × 25) ÷ 100
Result:
- Final Concentration = 0.5 M
The student can quickly verify the concentration without manual calculations.
