General Chem. Problem
« on: October 27, 2007, 10:50:51 PM »
Can someone please help me with this?

A 2.20 g sample of an unknown acid (empirical formula = C3H4O3) 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?
