Consider the following chemical reaction: NH4HS(s) → NH3(g) + H2S(g). When 0.020 moles of NH4HS are placed in a 2.0 liter container and heated to 127° Celsius, all of the solid decomposes. Given that R = 0.0821 liter atmospheres per mole Kelvin, which of the following is the pressure in atmospheres inside the container?
