Limitations of Avogadro’s Law
The limitations of Avogadro’s law is mentioned below:
- Avogadro’s law is appropriate for ideal gases, but for real gases, it only gives an approximation. The divergence of real gases from ideal behavior increases with high temperature and low pressure.
- Gaseous molecules with lower molecular masses such as helium, hydrogen, etc. follow Avogadro’s law more than gaseous molecules with heavier molecular masses.
- It is not applicable for solids and liquids, it is only applicable for gases.
- Avogadro’s law doesn’t work for highly dense or very light gases.

Avogadro’s Law
Avogadro’s Law was invented by Amedeo Carlo Avogadro in 1811. He was an Italian chemist and mathematician physicist. He said that, at constant temperature and pressure, two different ideal gases with similar volumes must contain an equal number of molecules. This law can be derived from the ideal gas equation.
In this article, we will discuss Avogadro’s law, its formula, derivation, application, and other aspects facts related to it in detail.
