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

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?
