Question

Using the following chemical formula, N2+3H2-->2NH3, how many moles of ammonium are produced when 3 moles of nitrogen react with hydrogen?

A.6 moles of ammonium

B.1.5 moles of ammonium

C.9 moles of ammonium (picked this one)

D.9 moles of nitrogen

Answer 1

6 moles of ammonia will be produced. The mole to mole ratio of n2 to nh3 is 1:2. Thus, 3 moles N2 yields 6 moles of NH3 in presence of excess hydrogen.
