Question

4 NH3 +5 02 +4NO + 6H2O
When 70.25 grams of NH3 react, how many moles of H20 are produced?

Answer 1

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 * $\frac{6molH_2O}{4molNH_3}$ = 6.19 mol H₂O
