Proposal for the unit of type of substance and the way it can be used

In the material world there is a great need for measuring different physical quantities. We measure for example seven basic quantity ; the mass (kg), the length (m), the time (s), the electric current(A), the thermodynamic temperature (K), the luminous intensity (cd) and the amount of substance (mole). All these units are connected with the atoms or the fields. Particular attention in the article is devoted to differences in empirical, chemical and molecular formulas, and the different properties of the substances they represent, resulting inthe need for more detailed differentiation. Therefore, we say that each of them describes different type of substance. When such a notion of a type of substance is introduced, which presents a certain physical quantity, it is necessary to ask the question of their measurement as each physical quantity must be measurable. Therefore, the physical quantity of a substance must also have its own name, its amount and its metering unit. The article deals with a measurement system for the type of substance, based on protons, neutrons and electrons, and a new measurement unit is introduced, boscovich (B). The name for the unit comes from a mathematician, astronomer, geodesist, physicist, philosopher, Jesuit Roger Joseph Boscovich and the name for type of substance S, comes from the radio chemist Frederic Soddy. For example, ethanol (chemical formula C2H6O and its molecular formula C2H5OH) can be expressed as S = 26.0020 0026 0033 B, while dimethylether (the same chemical formula C2H6O as ethanol and its molecular formula CH3OCH3) as S = 26.0020 0026 0044 B. The formula for the calculation of the type of substance S is presented.
