Answer:
One mole of oxygen gas, which has the formula O2, has a mass of 32 g and contains 6.02 X 1023 molecules of oxygen but 12.04 X 1023 (2 X 6.02 X 1023) atoms, because each molecule of oxygen contains two oxygen atoms.
Explanation:
Here we have to choose the partial pressure exerted by the air in the given sample among the given options.
The partial pressure of the air in the sample is C. 96.82 kPa.
As per the Dalton's law of partial pressure the total pressure of the gas in the pool (P) is equivalent to the summation of the partial pressure of water vapor and air pressure.
Mathematically we may write:

Now the 
Or, P_{Air}[/tex] = (100.18 - 3.36) kilopascals
Or, P_{Air}[/tex] = 96.82 Kilopascals.
Thus the partial pressure of the air in the sample is C. 96.82 kPa.

I believe that it loses energy, as it is moving away from the main power/control source.
