CHEMISTRY----> If aqueous solutions were made with the following molal concentrations:?

I'm not sure but if the compound has ionic bondings then it takes more energy to break the bond. So e) is not the answer. There is 7 bonds in a) so I think that is the answer. Though c) has the largest number of moles, there is only 3 bonds in one compound. I'm not sure about my answer.. But hope it helps somehow. :)
