Ammonia gas is synthesized according to the balanced equation below.

N2(g) + 3 H2(g) → 2 NH3(g)

If 1.55 L N2 react with 4.92 L H2, what is the theoretical yield (in liters) of NH3? Assume that the volumes of reactants and products are measured at the same temperature and pressure.

a) 4.93 L
b) 3.28 L
c) 1.55 L
d) 6.42 L
e) 3.10 L
