A definite amount of solid NH4HS is placed in a flask already containing ammonia gas at a certain temperature and 0.1 atm pressure. NH4HS decomposes to give NH3 and H2S and at equilibrium total pressure in flask is 1.1 atm . If the equilibrium constant K, for the reaction NH4HS(s) = NH3(g) + H2S(g) is represented as z x 10-1 then find the value of . z.
