Asked by Ashley
How do I calculate the concentration of KmNO4 when..
Initial Volume is 50mL
0.11g sodium oxalate
Volume of KMnO4 used to titrate oxalate and acid= 34.0 mL
Volume of KMnO4 used to titrate acid only= 0.10 mL
Please help me
Thank you!

Write the equation between C2O4^2 and MnO4^- and balance it.
Convert 0.11 g Na2C2O4 to moles. moles = grams/molar mass.
Use the coefficients in the balanced equation from above to convert moles oxalate to moles permanganate.
Then M MnO4^- = moles MnO4^-/L MnO4^-
