What is the Relationship between a Mole and Avogadro's number Avogadro's number Atoms and molecules are so small in size that they cannot be counted individually. The chemists use the unit mole for counting atoms, molecules or ions. It is represented by n. A mole represents 6.022 × 1023 particles. Example: 1 mole of atoms = 6.022 × 1023 atoms. 1 mole of molecules = 6.022 × … [Read more...] about What is the Relationship between a Mole and Avogadro’s number
