Ok so N2+O2=2NO and my delta h is 180.5 kJ I need to know. If I react 10 g of nitrous gas with excess oxygen how many grams of N
itrogen monoxide will be produced
1 answer:
Answer:
21.6 grams
Explanation:
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 *
= 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
