Chapter 4, Problem 54QAP

A wire weighing 0.250 g and containing 92.50% Fe is dissolved in HCI. The iron is completely oxidized to Fe³⁺ by bromine water. The solution is then treated with tin(II) chloride to bring about the reaction

${\text{Sn}}^{\text{2}+}\left(aq\right)+{\text{2Fe}}^{\text{3}+}\left(aq\right)\to {\text{2Fe}}^{\text{2}+}\left(aq\right)+{\text{Sn}}^{\text{4}+}\left(aq\right)+{\text{H}}_{\text{2}}\text{O}$If 22.0 mL of tin(II) chloride solution is required for complete reaction, what is the molarity of the tin(ll) chloride solution?
