You need 1 mole of nitrogen and 3 moles of hydrogen to make 2 moles of ammonia. If we multiply these numbers by 2, we can also say you need 2 moles of nitrogen and 6 moles of hydrogen to make 4 moles of ammonia. (And you'd have 1 mole of nitrogen left over.) And that's the answer: you'd get 4 moles of ammonia.

Find the limiting reagent by looking at the number of moles of each reactant. Determine the balanced chemical equation for the chemical reaction. Convert all given information into moles (most likely, through the use of molar mass as a conversion factor). Calculate the mole ratio from the given information.
