4nh3+5o2-->4no+6h20 What is the total number of moles of h2o produced when 12 mole of nh3 is completely consumed?

18 mol

Step-by-step explanation:

Step 1. Balanced equation

4NH₃ + 5O₂ ⟶ 4NO + 6H₂O

Step 2. Calculation:

You want to convert moles of NH₃ to moles of H₂O

The molar ratio is 6 mol H₂O:4 mol NH₃

Moles of H₂O = 12 mol NH₃ * (6 mol H₂O/4 mol NH₃)

Moles of H₂O = 18 mol H₂O

The reaction will form 18 mol of H₂O.
