The mole is important because it allows chemists to work with the subatomic world with macro world units and amounts. Atoms, molecules and formula units are very small and very difficult to work with usually. … Defining the mole in this way allows you change grams to moles or moles to particles.
In general, one mole of any substance contains Avogadro’s Number of molecules or atoms of that substance.
If you divide the charge on a mole of electrons by the charge on a single electron you obtain a value of Avogadro’s number of 6.02214154 x 1023 particles per mole.
This relationship was first discovered by Amadeo Avogadro (1776-1858) and he received credit for this after his death.Oct 23, 2013…..
