Step 1.
A sample of impure tin of mass of is dissolved in strong acid to form
. The solution is then titrated with a solution of, which is reduced to
. The corresponding reaction is,
is dissolved in strong acid to form. The solution is then titrated with a solution of, which is reduced to. The corresponding reaction is,
The number of moles of solution is calculated by the formula,
solution is calculated by the formula,
Substitute the value of concentration and volume of $\mathrm{NO}_{3}^{-}$solution in the above equation.
According to the chemical equation, acid and tin react in the molar ratio of
.
.Since 2 moles of react with 3 moles of
react with 3 moles of 
Therefore, 
of react with
