Avogadro (molecule)
Avogadro's number, approximately \(6.022 \times 10^{23}\), is a fundamental constant that represents the number of molecules or atoms in one mole of a substance. This concept is vital in chemistry because it allows scientists to convert between the number of particles and the mass of a substance. For example, one mole of carbon atoms contains about \(6.022 \times 10^{23}\) carbon atoms and weighs about 12 grams. Avogadro's number helps quantify the relationship between the microscopic world of atoms and the macroscopic measurements we can observe in everyday life.
