All chemical reactions occur in numbers, such as in number of atoms, ions, or molecules interacting. They are so small to be counted. So, Avagadro’s number is used which is equal to the molar mass of any substance expressed in grams.
This means Avogadro’s number (NA) is helpful in interconversion between mass, molar mass, and number of particles, etc. It is also used to relate the below entities:
In simple words, Avagrado’s number enables chemists to relate different chemical species. It has all the stoichiometric aspects of a chemical reaction. NA= 6.022 x 1023 is commonly used in stoichiometry and it is also sometimes called chemist dozen.
