At an underwater depth of 76 m the pressure is 8.35 atm. What would the mole fraction of oxygen have
to be in order for a SCUBA diver to experience a partial pressure of 0.21 atm oxygen in the breathing
mixture, the same as it is in air at 1.0 atm?
17. Suppose 1.000 r-1 103 moles of oxygen gas (03) is compressed into a steel tank that has a volume of 45.0 L.
