Oxygen Moles: Atoms vs. Molecules - Understanding Avogadro's Number
A mole of any substance contains 6.022 x 1023 atoms or molecules. This number is known as Avogadro's number.
Therefore, a mole of oxygen (O2) contains 6.022 x 1023 molecules of oxygen. However, since each oxygen molecule (O2) consists of two oxygen atoms, a mole of oxygen contains 2 x 6.022 x 1023 = 1.2044 x 1024 oxygen atoms.
