Problem

A sample of impure tin of mass 0.531 g is dissolved in strong acid to give a solution of Sn2+. The solution is then titrated with a 0.0448 M solution of NO3, which is reduced to NO(g). The equivalence point is reached upon the addition of 3.73×10−2 L of the NO3 solution. Find the percent by mass of tin in the original sample, assuming that it contains no other reducing agents.
