what is the molar mass of an acid if 25 gms of the aci requires 28.32 ml of 0.1M NaOH to neutralize it?

is this possible?  if the acid formula/name is not given how to get the molar mass of an acid?

It is possible to answer it.
You know moles = mass / molar mass
so molar mass = mass/ moles
Now in the question mass of acid is given. However they have not mentioned about how many H⁺ or protons are given in the acid.This must be mentioned because only then you can write a balanced equation to know the moles of the acid.
Lets take it monoprotic like HX
HX + NaOH ----> NaX + H₂O
Moles of NaOH = moles of acid
Moles of NaOH = M * V(L) = 0.1 * 28.32 * 10^-3 L = moles of the acid
Molar mass = mass /moles = 25.0 g/moles of the acid.
You may not get the right answer because I assumed acid as monoprotic.
