MnO4−(aq)+5 H2C2O4(aq)+6 H+(aq)→2 Mn2+(aq)+10 CO2(g)+8 H2O(l) The reaction between MnO4−(aq) and H2C2O4(aq) in acidic solution is represented above. In a titration experiment, a 0.040 M solution of KMnO4(aq) is added from a buret to an acidified sample of H2C2O4(aq) in a flask. The endpoint of the titration is determined by the appearance of a faint pink color in the mixture. Initial buret reading 6.09 mL Final buret reading 26.09 mL Based on the data in the table above, how many moles of H2C2O4(aq) were in the sample?
