Why is the value of Avogadro's number `6.022 xx 10^(23)` and not any other value ?

Explanation

It represents the number of atoms in one gram atom of an element or the number of molecules in one gram mole of a compound. If we divide the atomic mass of an element by actual mass of its atom, the value is `6.022 xx 10^(23)`. Similarly, by dividing the molecular mass of a compound by the actual mass of its molecules, the same result is obtained.
