A 0.1801 g iron ore sample was dissolved in hydrochloric acid and the iron was obtained as Fe2*(aq). The iron solution was titrated with Ce4+ solution according to the balanced chemical reaction shown below. After calculation, it was found that 0.0227 g of iron from the ore reacted with the cerium solution. Ce4*(aq) + Fe2*(aq) – Ce³*(aq) + Fe³*(aq) Calculate the mass percent of iron in the original ore sample. Please round your answer to the tenths place.
