48.2 grams of ammonia reacts with 13.4 grams of oxygen gas and produces nitrogen monoxide
If the actual amount of NO produced is 8.2 grams, what is the percent yield
48.2 grams ammonia make ~84.9 grams NO
13.4 grams oxygen gas makes ~10.1 grams NO
Theoretical = 10.1 grams
(8.2 / 10.1) x 100 = ~81.2%
