    Photoelectron spectroscopy is typically performed in a vacuum chamber with a pressure of 1.00 x 10^-7 torr at 25 degrees C. If the moles of gas that are present in this vacuum chamber are due to air, what mass of oxygen gas is still in the chamber? The mole fractions of nitrogen and oxygen gas in air are 0.78084 and 0.20942, respectively and the chamber volume is 700 L.
