In response to the cleaner’s call for reinforcing basic knowledge, a series on basic knowledge has been launched: Basic Knowledge of Inorganic Chemistry 01 – “Amount of Substance” is a physical quantity that measures the number of particles contained in a certain collection of particles. Amount of substance is one of the 7 base physical quantities in the International System of Units. In the International System of Units, the symbol for amount of substance is n, with the unit being mole; that is, n = N/NA. It is a physical quantity that connects microscopic particles with macroscopically measurable substances. It indicates the number of particles contained in a substance.
