Avogadro's law

Avogadro's law
Avo·ga·dro's law .av-ə-.gäd-(.)rōz-, .äv-, -.gad- n a law in chemistry: equal volumes of all gases at the same temperature and pressure contain equal numbers of molecules called also Avogadro's hypothesis
Avo·ga·dro .av-ə-'gäd-(.)rō, .äv- Count Amedea (1776-1856)
Italian physicist and chemist. Avogadro is considered one of the founders of physical chemistry. In 1811, he made his outstanding scientific contribution: his hypothesis, now accepted as a scientific law, that equal volumes of gases at the same temperature and pressure contain the same number of molecules. This hypothesis was a landmark in 19th-century chemistry and is one of the basic concepts of modern chemistry.

* * *

equal volumes of all perfect gases at the same temperature and pressure contain the same number of molecules or, in the case of monatomic gases, of atoms.
