Avogadro’s number

Avogadro’s number is a fundamental constant in chemistry and physics, representing the number of particles-such as atoms, molecules, or ions-in one mole of a substance. Its value is approximately 6.022 x 10²³, serving as a bridge between the atomic scale and the macroscopic world. This key concept is essential for stoichiometric calculations, molecular chemistry, and understanding the quantitative relationships in chemical reactions.
