First we look at the phase, noting that gas will have highest entropy, and solid the least entropy. All our compounds are in gas form, next we look at how many elements make up the compound, more elements------> more entropy.  If compounds are made up of same number of elements, we then look at their overall mass. Whichever has the highest molar mass, that's the one that will have the highest entropy.
