Stoichiometry of Ammonia Production

Hard General Chemistry Stoichiometry And Chemical Reactions

A reaction between nitrogen (N2) and hydrogen (H2) forms ammonia (NH3) according to the following balanced equation:

N2(g) + 3H2(g) → 2NH3(g)

If you start with 10.0 grams of nitrogen and an excess of hydrogen, how many grams of ammonia can you theoretically produce? (Molar masses: N = 14.01 g/mol; H = 1.008 g/mol; NH3 = 17.03 g/mol)
