`5.0 g` of a sample containing `(NH_(4))_(2) SO_(4)` & inert impurity `(X)` was boiled with excess of `NaOH` and the `NH_(3)(g)` so produced was absorbed in `200ml` of `0.5 M H_(2)SO_(4)` solution in another vessel. The unreacted `H_(2)SO_(4)` required `400ml` of `0.4 M` solution of `NaOH` for exact neutralization. Calculate weight `%` of nitrogen in given sample
