Given the reaction: 4NH3 + 502 4NO + 6H2O
Ainat [17]

Answer:

\frac{4}{5} moles

Explanation:

The reaction equation is given as:

      4NH₃   +  5O₂  →  4NO  +  6H₂O

The number of moles of O₂ that completely reacted is given as 1 mole

To solve this problem, we are going to use a stoichiometric approach from the balanced reaction equation:

         5 moles of O₂ will react completely to produce 4 moles of NO

        1 mole of O₂ will therefore react to produce  x mole of NO

               5x  = 4

                 x  = \frac{4}{5} moles of NO
