What is the Avogadro’s Law Calculator?

The Avogadro’s Law Calculator helps users determine the final volume of a gas when its number of moles changes, keeping temperature and pressure constant. By entering the initial volume, initial moles, and final moles, the calculator uses Avogadro’s law V1n1=V2n2\frac{V_1}{n_1} = \frac{V_2}{n_2}n1​V1​​=n2​V2​​ to compute the final volume. This is useful for chemistry students and educators to quickly understand gas behavior without manual calculation.

How to Use:

1. Enter Initial Volume (V₁, L): Input the starting volume of the gas in liters.
2. Enter Initial Moles (n₁, mol): Input the number of moles at the initial state.
3. Enter Final Moles (n₂, mol): Input the number of moles at the final state.
4. Click “Calculate”: The calculator computes the final volume V2=(V1×n2)/n1V₂ = (V₁ × n₂) / n₁V2​=(V1​×n2​)/n1​.
5. Review Result: The output shows the final volume in liters, providing a clear reference for Avogadro’s law calculations.
