Answer:

The answer is in the explanation.

Explanation:

A titration of H₂X with KOH produce:

H₂X + 2KOH → 2H₂O + K₂X

It is possible to obtain the moles of H₂X because the moles of KOH are the spent volume of the titration in liters × 0,455M. As for a complete titration of H₂X moles you need twice moles of KOH you know the moles of KOH obtained are half H₂X moles.

As you know the mass of the solid acid that you titrate and molar mass of acid is:

mass of acid / moles of acid. You can determine the molar mass of the unknown acid.

I hope it helps!
