One method to produce nitrogen in the lab is to react ammonia with copper (ii) oxide: nh3(
g. + cuo(s) cu(s) + h2o(l) + n2(
g. after using 40.0 grams of nh3, 15.5 grams of n2 are produced. what is the percent yield of nitrogen in the reaction?

47.05% is the percent yield of nitrogen in the reaction.

Explanation:

Theoretical yield of nitrogen gas = x

Moles of ammonia =

According to reaction,2 moles of ammonia gives 1 mol of nitrogen gas.

Then 2.3529 mol of ammonia will give:

of nitrogen gas

Mass of 1.1764 moles of nitrogen gas,x = 1.1764 mol × 28 g/mol=32.94 g

Experiential yield of nitrogen gas = 15.5 g

Percentage yield:

47.05% is the percent yield of nitrogen in the reaction.
