) A 3.0 L flask containing 2.0 mol O2 and 1.0 mol N2 is in a room that is at 22.0° What is the total pressure inside the flask? What is the mole fraction of the nitrogen in the flask? The flask is then cooled and the pressure drops. What happens, if anything, to the mole fraction of the nitrogen at the lower temperature?  A 1.0 L volume of liquid water is introduced in to the flask containing both gases. The pressure is then measured 45 minutes later.  Would you expect the measured pressure to be higher or lower?
