Iron in the form FeC12 can be determined by bitration with potassium dichromate: 6 FeCl2(aq) + K2Cr207(aq) + 14 HCl(aq) →6 FeCl3(aq) + 2 CrC13(aq) + 2 KCl(aq) + 7 H2O(1) An iron sample of mass 0.800 g required 18.80 mL of 0.0120 M K2Cr207(aq) to reach the end point. How many moles of FeCl2 were in the sample? A) 1.43 x 10-2mol B) 1.35 10-3 mol C) 3.75 10-5 mol D) 2.26 10-4 mol E) 1.13 10-4 mol OA OB O.C OD OF
