| Abstract: | Retrospective the historical of how the stoichiometric changed from macro level by to the microscopic particles level as well as of the the origin of amount of substance,mole and the Avogadro＆#39;s number.Analysis the difference between the amount of substance and mole.Noted the amount of substance should be defined a quantity which count particles of matter and the mole is the amount of substance of a system.These conclusions are guiding role on breakthrough teaching difficulties. |
