What is the Avogadro’s Law Calculator?

The Avogadro’s Law Calculator helps you determine the relationship between the volume and the number of moles of a gas at constant temperature and pressure using V₁/n₁ = V₂/n₂. By entering the known initial and final values and leaving one field blank, the calculator computes the missing value—whether it’s volume or moles. This tool is useful for students, teachers, and anyone working with gas law problems, allowing quick, accurate calculations and better understanding of gas behavior.

How to Use:

1. Enter Initial Volume (V₁): Type the starting gas volume.
2. Enter Initial Moles (n₁): Type the starting number of moles.
3. Enter Final Volume (V₂) or Moles (n₂): Provide the known final value, leaving the unknown blank.
4. Click “Calculate”: The calculator applies Avogadro’s Law to find the missing variable.
5. Review the Result: The output shows the calculated volume or moles with a clear, precise value.
