A 1.2516 gram sample of a mixture of CaCO3 and Na2SO4 was analyzed by dissolving the sample and completely precipitating the Ca2+ as CaC2O4. The CaC2O4 was dissolved in sulfuric acid and the resulting H2C2O4 was titrated with a standard KMnO4 solution. The titration required 35.62 mL of 0.1092 M KMnO4. Calculate the number of moles of H2C2O4 that reacted with the KMnO4. Calculate the number of moles of CaCO3 in the original sample. Calculate the percentage by weight of CaCO3 in the original sample.
