Answer:

6.19 mol H₂O

Explanation:

  • 4 NH₃ + 5O₂ → 4NO + 6H₂O

First, we convert 70.25 grams of NH₃ into moles, using its molar mass:

  • 70.25 g ÷ 17 g/mol = 4.13 mol NH₃

Then we convert 4.13 moles of NH₃ into moles of H₂O, using the stoichiometric coefficients of the balanced reaction:

  • 4.13 mol NH₃ * [tex]\frac{6molH_2O}{4molNH_3}[/tex] = 6.19 mol H₂O
