Robert Avogadro

Robert Avogadro was an Italian scientist best known for Avogadro's Law, formulated in 1811. This law states that equal volumes of gases, at the same temperature and pressure, contain the same number of molecules. It helped scientists understand the relationship between gas volume and molecular quantity, laying the groundwork for modern chemistry. Avogadro’s work increased our understanding of atomic and molecular theory, influencing how we measure and think about gases in scientific and industrial applications. His contributions remain fundamental in chemistry, particularly in the concept of the mole and Avogadro’s constant.
