A 0.1362g iron ore sample was dissolved in hydrochloric acid and the iron was obtained as Fe^2+(aq). The iron solution was titrated with Ce4+ solution according to the balanced chemical reaction shown below. After calculation, it was found that 0.0238g of iron from the ore reacted with the cerium solution.
Ce^4+(aq) + Fe 2+(aq) -> Ce^3+(aq) + Fe^3+(aq).
Calculate the mass percent of iron in the original ore sample. Please round your answer to the tenths place.
