Approx. 1.66xxN_A1.66×NA SO_2SO2 molecules, where N_A="Avogadro's number, "6.022xx10^23NA=Avogadro's number, 6.022×1023.

Explanation:

By solving the Ideal Gas equation, we know that at "STP"STP 22.4*L22.4L of "Ideal Gas"Ideal Gas contains "Avogadro's Number",N_AAvogadro's Number,NA of molecules.

And thus the number of sulfur dioxide molecules is (36.6*L)/(22.4*L)xxN_A36.6L22.4L×NA, whatever this is. Capisce?
