in 1909 fritz haber discovered the workable conditions under which nitrogen, n2(g), and hydrogen, h2(g), would combine to produce ammonia. the conditions included medium temperature (~500oc), very high pressure (~351kpa), and an iron catalyst. the reaction is represented by the equation:
n2(g) + 3h2(g) → 2nh3(g)
how many moles of nitrogen are needed to produce 1.20 moles of ammonia gas?
a) 0.60 mol n2
b) 1.21 mol n2
c) 1.67 mol n2
d) 2.40 mol n2
