The equilibrium constant (Kc) for the gas phase reaction 2 NH3 --> N2 + 3 H2 is 3 x 10-3 at some temperature. The reaction is started by placing a sample of ammonia in an empty one liter flask. When equilibrium is established there is 0.010 mole of N2 present. How much ammonia was originally added to the flask?
