for HC2H3O2, is there only one mole of H+ or 4 to calculate the equivalent mass? I'm thinking one, but want to double check.

The structure is CH3COOH. Only the last H is replaceable. So it might better be written: C2H3O2-H+. Only one. Trust me.

Equivalents are usuaully referring to dissociable ions. In this case there is only one H+, therefore you need only one equivalent of base to neutralize.
You would use 4 only if you are calculating mass of the compound. Just to remind you, acidic Hs are listed first almost always.
