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
