What apparent mass and true mass of CO2 will the resulting reaction yield?note of the following information:• Use the mass of CO2 you calculate above as the apparent mass. No need to convert the masses of CaC204 and KMNO4 into true masses first.• The unbalanced chemical equation of the redox reaction is as follows:C2042- + MnO4" + H* → CO2 + Mn²+ + H2OThe pertinent formula masses are as follows:ReagentFormula Mass (g/mol)CaC204128.097KMNO4158.03CO244.0095• The formula for the true mass is as follows:

Given reaction of CaC2O4 with KMnO4: C2O42- + MnO4- + H+ → CO2 + Mn2+ + H2O
