The empirical formula is the simplest whole number ration that defines constituent atoms in a species. The molecular formula is always a multiple of the empirical formula.
Molecule Formula = 78.0 • g • mol ^ -1 = n(12.011 + 1.00794) • g • mol ^ -1
78
N = ——————————- = 6
12.011 + 1.00794
Molecular Formula = C6H6
