A 20.00-mL sample of aqueous oxalic acid, H2C2O4, was titrated with a 0.09113-M solution of potassium
permanganate.
2MnO4
−(aq) + 5H2C2 O4
(aq) + 6H+(aq) ⟶ 10CO2
(g) + 2Mn2+(aq) + 8H2 O(l)
A volume of 23.24 mL was required to reach the end point. What is the oxalic acid molarity?

Answer:
Molar Mass of potassium permanganate = 158.034
= 0.09113 × 158.034 = 14.4
=20 + 14.4 + 23.24
= 57.642g
Molarity = moles of solute/Litres of the Solution
= 0.09113/0.0576
= 1.582m/L
