2.00 g calcium tablet sample is determined by precipitating CaC2O4, dissolving this in acid, and titrating the oxalate with 0.0200 M KMnO4. The formula reaction is 5 H2C2O4 + 2 MnO4- + 6 H+ ->10 CO2 + 2 Mn2+ + 8 H2O What percent of CaO is in the sample, if 35.6 ml KMnO4 is required for the titration?
