Question

I need help calculating the "titre" for both trials please (shown in the first picture).

In the first part of this experiment, you made a 100.00 mL solution of sodium oxalate, Na2C2O4. Please complete the table below. Mass of weighing funnel and Na2C204 (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. Unrounded Rounded 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 21.10 Final burette reading (mL) 50.00 36.80 Titre (mL)
