Answer:

21.6 grams

Explanation:

  • N₂ + O₂ → 2NO

First we <u>convert 10 g of N₂ into moles</u>, using its <em>molar mass</em>:

  • 10 g ÷ 28 g/mol = 0.36 mol N₂

Then we <u>convert 0.36 moles of N₂ into moles of NO</u>, using the <em>stoichiometric coefficients of the balanced reaction</em>:

  • 0.36 mol N₂ * \frac{2molNO}{1molN_2} = 0.72 mol NO

Finally we <u>convert 0.72 NO moles into grams</u>, using its <em>molar mass</em>:

  • 0.72 mol NO * 30 g/mol = 21.6 g
