One mole of atoms or of molecules means the Avogadro number of atoms or molecules (of chemical elements or compounds) respectively. Avogadro number is 6.022 * 10²³.
The mole concept is very useful in subjects like gas laws related to volume, pressure, temperature, concentrations, depression of freezing point, elevation of boiling point, partial pressures, solubility etc. The concentrations of Acids and Bases are expressed in terms of Molar concentrations. Reaction related arithmetic and reactivity constants are calculated using molar concentrations. Thus they involve Avogadro number.
An ideal gas at standard temperature and pressure occupies 22.418 Liters of space per mole.
