The charge on these particles is -1 and mass of these particles is negligible.
Answer:
The right answer is "8.81 atm".
Explanation:
Given:
V = 5.00 L
Mass = 4900 g
MW = 32 g/mol
T = 350 K
Now,
Number of moles will be:



By using the ideal gas equation, we get
⇒ 
or,
⇒ 
By substituting the values, we get
