Problem- Ammonium hydrogen sulfide dissociates into ammonia and H2S. If solid NH4HS is placed in an evacuated flask at a fixed temperature it will dissociate until the total gas pressure is 500 torr. If additional ammonia is introduced into the equalibrium mixture without changing the temperature until the pressure is 700 torr, what is the partial pressure of H2S under these conditions? What is the final total pressurein the flask when the new equalibrium is reached?
