Avogadro (Avogadro's number context)

Avogadro's number, approximately \(6.022 \times 10^{23}\), is a constant that represents the number of individual particles (atoms, molecules, or ions) in one mole of a substance. It helps scientists count tiny particles by relating them to measurable amounts of material. For example, one mole of water contains about \(6.022 \times 10^{23}\) water molecules. This large number bridges the microscopic world of atoms and molecules with macroscopic quantities we can measure, making it essential for understanding and working with chemical reactions and substances.
