Dioxin empirical formula

A complex organic compound, with the name 2,3,7,8-tetrachlorodibenza-para-dioxin, belongs to a family of toxic compounds called dioxins. The empirical formula of a certain dioxin is C6H2OCl2. If the molar mass of this dioxin is 322 g/mol, what is its molecular formula ... 

High-resolution analyzers separate isobaric ions, thereby significantly increasing selectivity. For example, the resolution needed to separate the isobaric ions of hexa-chlorobiphenyl (Ci2H4 Clg) at mJz 357.8444 and a specific isotope of pentachloro-dibenzo-p-dioxin (C12H335CI337CI2O2) at miz 357.8519 is m/Am = 357.8519/0.0075 or -48,000, a difficult but doable task. It should be emphasized that isomers, by definition, have the same empirical formulae, and therefore chromatographic separation is required to observe and analyze the components of such mixtures.
