A 5.00 L N₂ gas sample at a pressure of 1.20 atm and temperature of 15.8ºC has a mass of 7.08 g. What is the mass of a 10.0 L H₂ gas sample at the same temperature and pressure as the N₂ gas sample?

(a) How many moles of N2 gas are in the sample?

(b) How many moles of H2 gas are in the sample?

(c) At a given temperature and pressure, 5.00 L of N2 are reacted with 10.0 L of H2 via the reaction N2 + 3 H2(g) → 2 NH3(g)

Which gas is in excess? How many liters of ammonia are formed? How many liters of the excess reactant remain after the reaction?
