Conner Weiss · Answer 1

P₄O₆

Explanation:

The molecular formula is a whole number multiple of the empirical formula. that is, if the mole wt is 219.9 gms/mole and the empirical formula weight is 110 gms/mole*, then the whole number multiple is 219.9/110 = 2 = > Molecular formula = > (P₂O₄) ₂ = > P₄O₆.
