A sample of iron ore is dissolved in acid, and the iron is converted to Fe2+ (iron II). The sample is then titrated with 57.30 mL of 0.03240 M Mn04- solution. The net ionic equation for the oxidation-reduction that occurs during titration is as follows: Mn04-(aq) + 5FE2+(aq) + 8H+(aq) --> Mn2+(aq) + 5Fe3+(aq) + 4H20(1) How many moles of Fe2+ were in the sample? O 2.269 x 10^-2 mol (2.269E-2 mol) O 7.563 x 10^-3 mol (7.563E-3 mol) O 9295.1 mol O 5 mol O 9.285 x 10^-3 mol (9.285E-3 mol)
