Solid ammonium iodide decomposes to ammonia and hydrogen gases at high temperatures. NH4I(s)NH3(g)+HI(g) The equilibrium constant for the decomposition at 400C is 0.215. Twenty grams of ammonium iodide is sealed in a 7.50-L flask and heated to 400C. (a) What is the total pressure in the flask at equilibrium? atm (b) How many moles of HI is produced? (c) How many moles of NH3 is produced? mol (d) What is the molar mass of NH4 ? g/mol (e) How many moles of NH4l is originally present in the flask? (f) How many moles of NH4 is is left at equilibrium? (g) How many grams of NH4l is left at equilibrium? g
