At equivalence point:
moles acid = moles base
Determine the molar mass:
The empirical formula weight of the unknown acid is 88.062 g/mol.
A 2.20-g sample of an unknown acid (empirical formula = C 3H4O3) is dissolved in 1.0 L of water. A titration required 25.0 mL of 0.500 M NaOH to react completely with all the acid present. Assuming the unknown acid has one acidic proton per molecule, what is the molecular formula of the unknown acid?
