They give us all this information associated with the titration of lithium hydroxide and sulfuric acid, which is irrelevant to answering the question.

So you may have fallen for calculating the sulfuric acid concentration, as i did, but we don't need it after all.
00:18
If we were to calculate it, i'll just review it.

We would calculate the moles sulfuric acid and divide by the volume and liters of sulfuric acid that was titrated.
00:28
The mole's sulfuric acid are calculated by taking the volume of the lithium hydroxide in mill liters, converting it to liters by dividing by 1 ,000, then multiplying by the molarity of the lithium hydroxide to get moles, and then dividing by 2 because it's a 2 -1 -mole relationship between lithium hydroxide and sulfuric acid.
00:50
We then divide those moles sulfuric acid by the 25 mil liters expressed as liters and get 0 .179 molar sulfuric acid.

Now for the actual part of the problem, it's still a 2 to 1 stoichiometric reaction with the other diprotic acid...
