Avogadro number

Avogadro's number, approximately \(6.022 \times 10^{23}\), is a fundamental constant in chemistry that represents the number of atoms, molecules, or particles in one mole of any substance. It serves as a bridge between the microscopic world of atoms and the macroscopic world we experience. For example, one mole of carbon contains about \(6.022 \times 10^{23}\) carbon atoms, which helps scientists quantify and compare different substances in chemical reactions. This concept is essential for understanding the relationships between mass, volume, and the number of particles in chemistry and helps accurately measure and predict outcomes in experiments.
