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.

The geometric shape of this molecule is
D. tetrahedral
Hope it will help :)
When the solution used begins to change color and stays the new color for at least 30 seconds we are able to tell that the solution has reached the end point of titration
