Avogadro's principle

Avogadro's Principle states that equal volumes of gases, at the same temperature and pressure, contain an equal number of molecules. This means that if you have two balloons of the same size and they are both at the same temperature and pressure, they hold the same number of gas particles, regardless of the type of gas inside. This principle helps us understand the behavior of gases and is fundamental in chemistry, especially when calculating reactions involving gases or determining their properties.
