A sample containing H₂C₂O₄ was dissolved and all of

A sample containing H₂C₂O₄ was dissolved and all of it used in a redox titration. What mass of H₂C₂O₄ was in the sample if it required 26.37 mL of 0.1420 M MnO4to react completely with H₂C₂O₄? They interact according to the redox reaction below.

5 H₂C₂O₄ (aq) + 2 (MnO₄)- (aq) + 6 H+ (aq) -> 10 CO₂ + 2 Mn₂ + 8 H₂O
