What is the molecular weight of K3[Fe(C2O4)3].3H2O? Use 19K39, 26Fe56, 6C12, 8O16 and 1H1 Select the closest answer

The end point of the titration of oxalate with permanganate ion can be observed when the color of the solution turns to

Calculate the percent C2O42- by weight in H2C2O4 Use 6C12, 1H1 and 8O16

(This question ties to question 18) The balanced reaction 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
