whats a formula unit?

anonymous · Answer

Formula unit is just the term referring to the smallest "piece" of an ionic compound. It is used just like the term atom is the smallest representative particle of an element or a molecule is the smallest representative particle of a molecular compound.

aaronq · Answer

regardless...  multiply the amount of moles by avogadros number, thats how many NaCl particles you would have, then if they want Na + Cl then multiply by 2
