Answer:
Final volume, V2 = 13.18 Liters
Explanation:
<u>Given the following data;</u>
Initial volume = 9.9 L
Initial temperature = 303 K
Final temperature = 403 K
To find the final volume, we would use Charles law;
Charles states that when the pressure of an ideal gas is kept constant, the volume of the gas is directly proportional to the absolute temperature of the gas.
Mathematically, Charles' law is given by the formula;
Where;
- V1 and V2 represents the initial and final volumes respectively.
- T1 and T2 represents the initial and final temperatures respectively.
Making V2 as the subject formula, we have;


<em>Final volume, V2 = 13.18 Liters</em>

Answer:
81.59%
Explanation:
First we <u>convert 107.50 g of NH₃ into moles</u>, using its <em>molar mass</em>:
- 107.50 g NH₃ ÷ 17 g/mol = 6.32 mol NH₃
Now we <u>calculate how many moles of NO would have been formed by the complete reaction of 6.32 moles of NH₃</u>:
- 6.32 mol NH₃ *
= 6.32 mol NO
Then we <u>convert 6.32 moles of NO to grams</u>, using its <em>molar mass</em>:
- 6.32 mol NO * 30 g/mol = 189.60 g NO
Finally we <u>calculate the percent yield</u>:
- 154.70 g / 189.60 g * 100% = 81.59%
