Thanks for your question!

The number of Avogadro is a constant discovered by Amedeo Avogadro. It has an approximate value of 6.022 • 1023.

The Avogadro number is widely used in chemistry since it is the precise number of atoms or molecules in a mole. Indeed, ONE mole of atoms or molecules represents 6.022 • 10^23 units of these. Similarly, a dozen eggs represents 12 eggs, even though it is said that there are only ONE dozen.
