Avogadro's Law: Equal Volumes, Equal Molecules

Definition

Avogadro's law

Avogadro's law states that equal volumes of all gases, measured under the same conditions of temperature and pressure, contain equal numbers of molecules.

This principle is grounded in the idea that the volume of a gas depends on the number of particles it contains, regardless of their type or size.
Whether the gas consists of single atoms (e.g., helium, He), diatomic molecules (e.g., oxygen, $O_2$), or larger molecules (e.g., carbon dioxide, $CO_2$), Avogadro's Law holds true.

Mathematical Expression of Avogadro's Law

The relationship described by Avogadro's Law can be expressed mathematically as: $$\frac{V_1}{n_1} = \frac{V_2}{n_2}$$ where:
1. $V_1$ and $V_2$ are the volumes of two gas samples.
