Answer:

6.19 mol H₂O

Explanation:

  • 4 NH₃ + 5O₂ → 4NO + 6H₂O

First, we<u> convert 70.25 grams of NH₃ into moles</u>, using its<em> molar mass</em>:

  • 70.25 g ÷ 17 g/mol = 4.13 mol NH₃

Then we <u>convert 4.13 moles of NH₃ into moles of H₂O</u>, using the <em>stoichiometric coefficients of the balanced reaction</em>:

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