A compound containing only sulfur and nitrogen is 69.6% S by mass; the molar mass is 184 g/mol. What are the empirical and molecular formulas of the compound?

i solved for empirical and got a 1:1 ratio so it would be SN.

for the molecular do i take 184/46.08 to get 3.99 or 4?
so it would be S4N4?

  1. Yes, assuming the S is reported as %S (as you have it written) and not %S8.
