A 60.0 mL sample of oxygen gas is collected over water at 25.0 degrees C. The total pressure inside the tube is 785.0 mm HG. The vapor pressure of water at 25.0 degrees C is 23.8 mm Hg. What is the pressure of the oxygen gas?

a 20-cm-long, cylindrical graphite (pure carbon) rod is inserted into an oxidizing atmosphere at 1145 k and 1.013 x 105 pa pressure. the oxidizing process is limited by the diffu- sion of oxygen counterflow to the carbon monoxide that is formed on the cylindrical surface.

water at room temperature is flowing through a pipe with pressure taps located 10 ft apart along one section of the pipe, which are connected to a mercury (s=13.6) manometer.
