A definite amount of solid `NH_(4)HS` is placed in a flask already containing ammonia gas at a certain temperature and 0.1 atm pressure. `NH_(4)HS` decompses to give ` NH_(3)` and `H_(2)S` and at equilibrium total pressure in flask is 1.1 atm. If the equilibrium constant `K_(P)` for the reaction `NH_(4)HS(s) iff NH_(3)(g)+H_(2)S(g)` is represented as `zxx10^(-1)` then find the value of z.
