How many ....
What do your mean? Sulfur monoxide, SO (or its dimer S2O2), sulfur dioxide, SO2, or sulfur trioxide, SO3?
Either way you slice it a molecule of SOx is one particle, and 1.80 mol of that particle is 1.8 times Avogadro's constant (the number of particles in a mole).
1.80 mol SOx x (6.022x10^23 molecules SOx / 1 mol SOx) = 1.08x10^24 molecules SOx
Now, if you mean "atoms" instead of the more generic "particles", that's a different story. For that you have to know which "sulfur oxide" you're talking about.
The answer is accurate. Don't be put off by the "thumbs down." It's the work of a troll.
