A solution was made by taking 1.250g of KMnO4 and dissolving it in enough water to make 1.000 liter of solution. This solution was used to titrate H2C2O4·2H2O, a very pure substance. In acidic media, the reaction is
MnO4-(aq) + H2C2O4(aq) + ___ CO2(g) + Mn2+(aq) + ____
How many mL of this solution are required to titrate a 0.480 g sample of H2C2O4·2H2O?
