Is it a lucky accident that avogadro's number of helium atoms weight exactly four grams?
No, it is not a lucky accident. An Avogadro's number of helium atoms do not weigh 4 grams: their mass is four grams and that is NOT the same thing. The mass is related to the Atomic Mass unit which is, essentially the number of protons and neutrons in an atom. More accurately, it is the weighted average for the atomic mass across the isotopes of the element - weighted according their abundance.
