what if you're not given the diprotic acid's experimental mass and are asked for the formula?

idk but i do know that you can save 5% or more on car insurance by switching to Geico

For anyone reading this in the future, all you have to do is balance the OH^- and the H2O with a 2 coefficient instead of a 3. So your dimensional analysis would end up having 1 mol H3X / 2 mol OH^-

For the first, why didn’t you round your answer to 53, because of the .5

How do you find the moles of the unknown acid?

The mols of the unknown acid will equal the mols of the added base at the end point of the titration (equivalence point).

52.5 rounded to 2 sig figs should be 53??? Or am I tripping

So.... crazy thing - there is a common convention that when rounding numbers that end in a 5 we round up half of the time and down half of the time - the easiest way to do this is to "round to the even" number so 52.5 rounds down to 52, and 53.5 rounds up to 54.
