A 40.0 g sample of solid ammonium carbonate is placed in a closed evacuated 3.00 L flask and heated to 400 degrees C. It decomposes to produce ammonia, water and carbon dioxide. The equilibrium constant, Kp, for the reaction is 0.295 at 400 degrees C.
How do I calculate the total pressure inside the flask at equilibrium at this temperature?
How do I calculate the number of grams of solid ammonium carbonate in the flask at equilibrium?
