(This questiоn ties tо questiоn 18) The bаlаnced reаction between oxalate and permanganate ion is shown below. 5C2O42- + 2MnO4 + 16H+ → 10CO2 + 8H2O + 2Mn2+ During the standardization of KMnO4, a 28.0 mL of KMnO4 has been used to neutralize 0.200 g of Na2C2O4 (MW = 134 g/mol). Based on the balanced reaction, determine the moles of permanganate KMnO4 in 28 mL Hint: Identify the mole ratio between oxalate and permanganate
