Question

Consider the reaction represented by the unbalanced equation: NH3 + O2 → NO + H2O. For every 4.67 mol of ammonia that reacts, _____ mol of oxygen is required.

a. 5.84

b. 18.68

c. None of these

d. 3.74

e. 4.67

Answer 1

Hi Anjela R.,

A balanced equation gives us 4NH₃ + 5O₂ -------> 4NO + 6H₂O.

We can now do a conversion:

4.67 mols NH₃ *(5mols O₂/4 mols NH₃) = 5.8375 or 5.84.

I hope this helps, Joe.
