Question
  1. Calculate the total pressure (in atm to 2 sf) in a container with 616 torr N2, 104 torr O2, and 40. torr CO2.
  2. Calculate the volume (in L to 2 sig figs) of 15.735 g CO2 gas if it is pressurized to 2.0 atm at 0.0°C.
  3. Calculate the pressure (in atm to 2 sig figs) of a balloon (initially at 25.0°C and 0.98 atm) after it is submerged into liquid nitrogen to a temperature of -196.0°C.

  4. Will the following conditions increase the solubility of the gas oxygen (O2) in solution (y/n)?

        1. An increase the temperature of the solution
        2. Replacing water with blood containing hemoglobin
        3. A decrease in the pressure of the room in which the water and N2 are located (ie, try the experiment on a mountain top instead of at sea level).

          5. Use table 6.1 below: The vapor pressure of water at various temperatures to answer the questions below.

          a. Water boils at sea level (Patm = 760 torr) at 100°C.  Estimate the temperature (in °C) at which water boils in Johnstown if the atmospheric pressure (Patm) is 701 torr.
          b. If you hang wet sheets outside on a clothesline on a sunny winter day when the temperature is 0°C, they will eventually dry.  Explain why using the table above.
          6. 
        4. Calculate the molecules of gas (to 2 sig figs) in a 0.75 L container that has a pressure of 814 mmHg at a temperature of 315 K.
