I did a redox titration. I need help calculating the concentration of my KMnO4 solution. So i first measured .2125 g of Na2C2O4 and put it into a flask. Next I transferred 250 ml of 1 M H2SO4 solution into the flask and dissolved the salt. I then titrated it with KMnO4 with 27.2 ml of KMnO4 solution. What is the concentration of my KMnO4 solution? Please show all the work.
