13 Αυγ 2022 · Just as a dozen implies 12 things, a mole (abbreviated as mol) represents 6.022 × 1023 things. The number 6.022 × 10 23, called Avogadro’s number after the 19th-century chemist Amedeo Avogadro, is the number we use in chemistry to represent macroscopic amounts of atoms and molecules.
A mole (mol) is a number of things equal to the number of atoms in exactly 12 g of carbon-12. Experimental measurements have determined that this number is very large: 1 mol = 6.02214179 × 10 23 things. Understand that a mole means a number of things, just like a dozen means a certain number of things-twelve, in the case of a dozen.
