Question

2. A closed vessel contains equal number of N2, and O2 molecules at Pmm of
pressure. If Nitrogen is removed from the system then what will be the
pressure?​

Answer 1

Answer:

p/2

Explanation:

As we know, the ideal gas equation is $$PV = nRT$$

Now since N2 is removed the total pressure would be equal to the partial pressure exerted by the O2 gas and vice versa. Therefore, the pressure after the N2 of any gas would be equal to P/2 mm of Hg.
