The mole is a fundamental unit in chemistry representing 6.022×10^23 particles (Avogadro’s number). It bridges the microscopic world of atoms to the macroscopic world of grams. One mole of a substance corresponds to its molar mass in grams (e.g., 1 mole of H2O ≈ 18 g). The mole concept is pivotal in stoichiometry, solution concentrations, and gas volume calculations.
