Answer:
22.5L
Explanation:
Given parameters:
Volume of N₂O₃ = 15liters
Unknown:
volume of oxygen gas = ?
Solution:
To solve this problem, we need to work from the known to unknown. The known is N₂O₃. We can find the number of moles from here.
Note: The condition is Standard temperature and pressure
Number of moles =
Number of moles of N₂O₃ = = 0.67moles
The equation of the reaction;
2N₂ + 3O₂ → 2N₂O₃
Since the equation is balanced;
2 moles of N₂O₃ is produced from 3 moles of O₂
0.67moles of N₂O₃ is produced from = 1.01 moles of O₂
Therefore;
Volume of O₂ = 1.01 x 22.4 = 22.5L
The balanced chemical reaction is:
<span>C6H12 + 9O2 = 6CO2 + 6H2O
We are given the amount of </span><span>C6H12 to be used for the reaction. THis will be the starting point for the calculations.
1.900 g </span>C6H12 ( 1 mol C6H12/ 84.18 g C6H12) ( 6 mol CO2 / 1 mol <span>C6H12) (44.01 g /mol ) = 5.96 g CO2
</span>1.900 g C6H12 ( 1 mol C6H12/ 84.18 g C6H12) ( 6 mol H2O / 1 mol <span>C6H12) (18.02 g /mol ) = 2.44 g H2O
