Avogadro's Law Volume Ratio Calculator

Avogadro's Law Volume Ratio Calculator

At the same temperature and pressure, equal volumes of any ideal gas contain the same number of molecules - one of the most elegant and useful relationships in gas chemistry.

Formula: V₁/n₁ = V₂/n₂

Example: 22.4 L containing 1 mole, if the mole quantity doubles to 2 moles at the same temperature and pressure, the volume also doubles to 44.8 L.

How to Use This Calculator

1. Enter the initial volume and initial mole quantity.
2. Enter the final mole quantity.

This relationship holds regardless of which specific gas is involved - it is exactly why gas stoichiometry problems can substitute volume ratios directly for mole ratios when temperature and pressure stay constant.
