Well, clearly it is #SnS_2#. Why?

Explanation:

By definition, the empirical formula is the simplest whole numer ratio that defines constituent atoms in a species. Normally we are given percentages, and use this mass percent to determine the elemental composition. Here, we are explicitly given the molar ratios, i.e. #Sn:S, 1:2#.
