What is the logic behind Avogadros Number?
In 1811, Amedeo Avogadro theorized that “equal volumes of all gases at the same temperature and pressure contain the same number of molecules.” Today, this is known as Avogadro’s Law. Experiments based on this principle eventually led to the calculation of the number of molecules in one cubic centimeter of gas. This number of molecules was determined to be roughly 6.02×1023; this was dubbed “Avogadro’s number.” What’s it good for? It helps us define the mole. What’s a mole? We found the official definition on ChemTeam’s page on The Mole and Molar Mass: “The mole is the amount of substance of a system which contains as many elementary entities as there are atoms in 0.012kilogram of carbon-12.” The number of atoms in 0.012kg of carbon-12 is 6.0221367×1023 — named Avogadro’s number. Put simply, one mole of any substance contains Avogadro’s number of molecules, atoms, or “ele
