What is the percent yield for the following chemical …

19/9/2017· 75% The first thing that you need to do here is to calculate the theoretical yield of the reaction, i.e. what you get if the reaction has a 100% yield. The balanced chemical equation "N"_ (2(g)) + 3"H"_ (2(g)) -> 2"NH"_ (3(g)) tells you that every 1 mole of nitrogen gas that takes part in the reaction will consume 3 moles of hydrogen gas and produce 1 mole of ammonia. In your case, you know
