Based on the Balanced Chemical Equation Shown Below, Determine the Mass

Multiple Choice

Based on the balanced chemical equation shown below, determine the mass percent of Fe³⁺ in a 0.7450 g sample of iron ore if 22.40 mL of a 0.1000 mol L^-1 stannous chloride, SnCl₂(aq) , solution is required to completely react with the Fe³⁺ present in the ore sample. The chemical equation for the reaction is: 2Fe³⁺(aq) + Sn²⁺(aq) → 2Fe²⁺(aq) + Sn⁴⁺(aq)
