Approx. #1.66xxN_A# #SO_2# molecules, where #N_A="Avogadro's number, "6.022xx10^23#.

Explanation:

By solving the Ideal Gas equation, we know that at #"STP"# #22.4*L# of #"Ideal Gas"# contains #"Avogadro's Number",N_A# of molecules.

And thus the number of sulfur dioxide molecules is #(36.6*L)/(22.4*L)xxN_A#, whatever this is. Capisce?
