Question

MnO₄^- can be used in a redox titration to determine the amount of H₂C₂O₄ in an unknown sample. Below is an unbalanced reaction that describes this process:

MnO₄^- + H₂C₂O₄ --> Mn²⁺ + CO₂

25.00 mL of a solution containing an unknown amount of H₂C₂O₄ (MW = 90.03 g/mol) required 18.31 mL of 0.1153 M MnO₄^-to react completely. Calculate the molarity of the original unknown H₂C₂O₄ solution.

NOTE: This is a redox titration, so remember to balance each half reaction and then add them together to arrive at the overall balanced reaction. To help you out, I will tell you that each C in H₂C₂O₄ has a 3+ charge. Also, if your overall balanced reaction doesn't have 8 waters on the right, you have done something incorrectly.
