A mixture of one mole each of H 2 , He and O 2 each are enclosed in a cylinder of volume V at temperature T. If the partial pressure of H 2 is 2 atm , the total pressure of the gases in the cylinder is:

Options

  1. A6   atm
  2. B38   atm
  3. C14   atm
  4. D22   atm

Correct answer

A. 6   atm

Step-by-step solution

P gas = n gas RT V as n ,   T   & V constant so P H 2 = P O 2 = P He = 2 atm So, P Total = P H 2 + P O 2 + P He = 6   atm
