The constant named after Amedeo Avogadro, known as Avogadro's number, is 6.022 x 10^23. This number represents the amount of constituent particles (usually atoms or molecules) in one mole of a substance.
Amedeo Avogadro is best known for his contribution to the field of chemistry, particularly for the development of Avogadro's hypothesis. In 1811, he proposed that equal volumes of gases, at the same temperature and pressure, contain an equal number of molecules. This idea helped to clarify the relationship between the volume of a gas and the number of particles it contains, laying the groundwork for the concept of the mole and Avogadro's number.
The constant was named in his honor to recognize his pivotal role in the understanding of molecular theory and the relationship between gas volumes and the number of molecules, which are fundamental concepts in chemistry and the study of chemical reactions.
