Question

I need help calculating the values of the molarity of KMnO4 solution and the averages please.

reaction equation --> 2 MnO4 + 5 C2O42− + 16 H+ → 2 Mn2+ + 10 CO2 + 8 H2O

Molarity of Na2C2O4 solution (M)
0.0233600
0.02336
TITRATION DATA
In the next part of the experiment, you used the standard solution of
sodium oxalate to standardize a solution of potassium permanganate,
KMNO4. The potassium permanganate was the titrant. Please complete
the table below.
Trial 1
Trial 2
Volume of Na2C2O4 solution pipetted (mL)
25.00
25.00
Initial burette reading (mL)
21.10
