A mole is a unit of measurement used in chemistry to express the amount of a substance. One mole of a substance contains approximately 6.022 x 1023 elementary entities, such as atoms, molecules, ions, or formula units.
This number is known as Avogadro’s number and represents the number of particles in one mole of a substance.
The mole allows chemists to easily convert between the mass of a substance and the number of particles it contains, facilitating quantitative analysis and stoichiometric calculations.
