The partial pressure of N2 in the air is 593 mm Hg at 1 atm. What is the partial pressure of N2 in a bubble of air a scuba diver breathes when he is 132 ft below the surface of the water where the pressure is 5.00 atm?

Partial pressure of at a depth of 132 ft below sea level is 2964 mm Hg.

Explanation:

It is known that 1 atm = 760 mm Hg.

Also,  

where,     = partial pressure of

                 P = atmospheric pressure

            = mole fraction of

Putting the given values into the above formula as follows.

        = 0.780

Now, at a depth of 132 ft below the surface of the water where pressure is 5.0 atm. So, partial pressure of is as follows.

                  =

                  = 2964 mm Hg

Therefore, we can conclude that partial pressure of at a depth of 132 ft below sea level is 2964 mm Hg.
