Avogadro
Definition
The surname of the celebrated Italian physicist and chemist Amedeo Avogadro (1776–1856), globally recognized for his fundamental contributions to the development of molecular theory. In exact sciences, his name is directly associated with 'Avogadro's number' and 'Avogadro's law', essential constants and structural principles defining the proportions between gas volume and the number of molecules contained at a given pressure and temperature.
