In the experiment, "Analysis of an iron Complex Salt" the following data was obtained for the analysis of oxalate. (6 pts) a) Calculate the percentage of CO- in the sample. b) Calculate the percent error, if the theoretical percentage of oxalate in the sample is 53.8%. 2 MnO (aq) + 5 C,O, 2- (aq) + 16 H* - 2 Mn2 (aq) + 10 CO, (g) + 8 H,O(1) Analysis for oxalate: Weight of sample 0.260 g Volume of KMno, solution used to titrate the oxalate 24.85 mL Molarity of KMnO solution 0.02500 mol/L
