An 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, the total pressure in the flask 1.1 atm. If the equilibrium constant Kp for reaction NH4H(S) ⇌ NH3(g) + H2S(g) is represented as z x 10^-1 then find the value of x.
