3 H2 (g) + N2 (g) --> 2 NH3 (g)

How many liters of ammonia gas can be produced from 10.0 L of N2 and
20.0 L of H2? Assume all gases are measured at the same temperature and pressure.

This is a limiting reagent problem but since reactants and products are gases you may take a shortcut and use volume as moles.
Using the coefficients in the balanced equation, convert 10.0 L N2 to L NH3. Do the same for 20.0 L H2. The answers will not agree; the correct answer in limiting reagent problems is ALWAYS the smaller value.
