- Chemistry 104 PLEASE HELP ME!! -
**DrBob222**, Sunday, May 5, 2013 at 3:27pmWrite and balance the equation.

2MnO4 + 5C2O4^2- ==> 10CO2 + 2Mn^2+ and you can finish but the coefficients are are what you need.

How much KMnO4 do you have? That's mols = M x L = 0.02L x 0.02M = ?

Use the coefficients above to convert mols KMnO4 to mols Na2C2O4.

Now convert mols Na2C2O4 to grams.

g = mols x molar mass.
