Phosphoric acid, H3PO4, is the active ingredient in certain commericial rust removers. What is the molarity of a phosphoric acid solution if 34.24 mL of 0.425 M KOH is required to titrate 23.6 mL of a phosphoric acid solution given the following reaction? H3PO4 (aq) + 3 KOH (aq) K3PO4 (aq) + 3 H₂O (1) Report the molarity to 3 sig figs in terms of M, but do not include units.
