Avogadro's number vs. the Kofh Number

Hi Kofh2u,Avogadro's number is defined by accepted convention to be the number of molecules in a mole of a substance. A mole is defined by accepted convention to be the weight in grams numerically the same as the molecular weight of the substance. These conventions became accepted because of the great conveniences they introduced. Because Avogadro's number and a mole are accepted conventions, you cannot argue that they are wrong, you can only suggest that they are insufficiently convenient and propose other conventions for consideration.--Percy
