WebThe most common isotope of carbon has an atomic mass of 12. There are rare forms of carbon that are heavier because they have extra neutrons, but we'll ignore them here. Thus 1 gram of carbon contains Avogadro's Number 12 carbon atoms. Likewise if we had 6.02 × 10 23 carbon atoms, we'd have 12 grams of carbon. Aha. Origin of the concept The Avogadro constant is named after the Italian scientist Amedeo Avogadro (1776–1856), who, in 1811, first proposed that the volume of a gas (at a given pressure and temperature) is proportional to the number of atoms or molecules regardless of the nature of the gas.
