A sample of impure tin of mass 0.523 gg is dissolved in strong acid to give a solution of Sn2+Sn2+. The solution is then titrated with a 0.0448 MM solution of NO3−NO3−, which is reduced to NO(g)NO(g) and the Sn2+Sn2+ is oxidized to Sn4+Sn4+. The equivalence point is reached upon the addition of 3.78×10−2 LL of the NO3−NO3− solution. Find the percent by mass of tin in the original sample, assuming that it contains no other reducing agents
