Question

I need help calculating the Molarity of the solution in the first picture please!!!

The complete reaction equation will show once the above questions have been completed.
2 MnO4- + 5 C20,²- + 16 H+ → 2 Mn2+ + 10 CO2 + 8 H,O
MASS OF SODIUM OXALATE
In the first part of this experiment, you made a 100.00 mL solution of sodium oxalate, Na2C204.
Please complete the table below.
Mass of weighing funnel and Na2C2O4 (g)
2.5366
Mass of weighing funnel (g)
2.2235
Mass of Na2C2O4 (g)
0.3131
MOLARITY OF SODIUM OXALATE SOLUTION
Now use the mass of sodium oxalate, and the volume of the solution, to calculate the molarity of the sodium oxalate
solution.
