O A chemical engineer determines the mass percent of iron in an ore sample by converting Fe to Fe in acid and then titrating Fe with MnO4. A 1.1081 g sample was dissolved in acid and titrated with 39.32 mL of 0.03190 M KMNO4. The balanced equation is SH (aq) + 5Fe (aq) + MnO4 (aq)-> 5 Fe (aq) + Mn (aq) + 8H20 (I) Calculate the mass percent of iron in the ore.
