Can someone please have me with this chemistry problem?

If HCl is a strong acid, and it is, and strong acids completely dissociate, is there any difference in the concentration (molarity) of H30+ ion and the concentration of HCl? For example, we call a solution 2.0 M HCl. Since HCl dissociates into separate ions, H+ (or H30+) and Cl-, wouldn't it be just as accurate to describe the solution as 2.0 M H30+?

    If you don't care at all what the anion in the solution is, sure, you can call it 2.0 M H3O+ if you want to. Frequently when dealing with net ionic equations, that's all you're worried about anyway.
