Mole: One mole of a substance (atoms, molecules, ions, or particles) is that quantity in number having a mass equal to its atomic or molecular mass in grams.

One mole of any substance contains 6.022 * 10^23 particles (atoms, molecules, or ions), which is termed as avogadro number or avogadro constant.
