A Titanium(IV) oxide (TiO2) is a white substance produced by the action of sulfuric acid on the mineral ilmenite (FeTiO3): FeTiO3 + H2SO4 >>>> TiO2 + FeSO4 + H2O Its opaque and nontoxic properties make it suitable as a pigment in plastics and paints. In one process, 8.00 x 10² kg of FeTiO3 yielded 3.67 x 103 kg of TiO2. What is the percent yield of the reaction?
