Explanation

A mole is defined as the amount of substance containing exactly 6.022 x 10^23 elementary entities (atoms, molecules, ions, etc.). This number is called Avogadro's number and serves as a bridge between the atomic scale and macroscopic measurements. It allows chemists to count particles by weighing them.
