Ammonia gas decompses to form nitrogen and hydrogen gases. NH3(g) → N2(g) + 3H2(g) If the nitrogen gas is collected in a rigid 2 liter metal cylinder at 22oC at 2.00 X 103 kPa pressure, how many moles of nitrogen gas (N2) does the cylinder contain? A) 1.63 moles B) 1.35 X 10 moles C) 1.42 X 102 moles D) 1.82 X 102 moles
