Quick Answer
Avogadro’s law is named after Amedeo Avogadro. It says that at the same temperature and pressure, equal gas volumes contain equal numbers of particles.
The Full Story
Avogadro’s law is named for the Italian scientist Amedeo Avogadro. In 1811, he proposed that equal volumes of gases, at the same temperature and pressure, contain equal numbers of molecules. This idea was crucial for understanding atomic and molecular weights and for developing modern chemistry. Avogadro’s work later helped lead to the concept of the mole and Avogadro’s number, about 6.02 × 10^23.
