Molar Dilution Calculator
Dilution is a common laboratory procedure used to reduce the concentration of a solution. Calculating dilution manually can lead to errors if not done correctly.
Our Molar Dilution Calculator uses the standard dilution formula to ensure precise results instantly.
What is Molar Dilution?
Molar dilution calculates how to dilute a concentrated solution to achieve a desired concentration.
Dilution Formula:
M₁V₁ = M₂V₂
Where:
- M₁ = Initial concentration
- V₁ = Initial volume
- M₂ = Final concentration
- V₂ = Final volume
What Does This Calculator Do?
It calculates any one unknown variable when the other three are provided.
Most commonly:
- Required initial volume (V₁)
Required Inputs
Typically:
- Initial concentration (M₁)
- Final concentration (M₂)
- Final volume (V₂)
Output
- Required volume of stock solution (V₁)
How to Use
Step 1: Enter Initial Concentration
Input M₁.
Step 2: Enter Desired Final Concentration
Input M₂.
Step 3: Enter Final Volume
Input V₂.
Step 4: Click Calculate
The tool calculates required stock volume.
Example
M₁ = 5 M
M₂ = 1 M
V₂ = 1 L
V₁ = (1 × 1) / 5 = 0.2 L
You need 0.2 L of stock solution.
