Answer:
The partial pressure of bar.
Explanation:
Given:
Volume L
Total pressure bar
Temperature of system K
Moles of nitrogen mole
Partial pressure bar
From ideal gas equation,
Where = gas constant
First finding partial pressure of nitrogen
bar
We know, total pressure is given by
bar
Therefore, the partial pressure of bar.
Answer:
37.5 moles of O2 needed
Explanation:
2 moles of C6H6 need 15 moles of O2
5/2 * 15 = 37.5 of O2 needed
