Question

1)Normal lung capacity is about 0.32L. On a cool fall day, the outside air has a temperature of 13°C while the temperature inside the lung at 37°C. The pressure outside the lung is 749 torr, and the pressure inside the lung is 733 torr. How many mL of air must be inhaled to fill the lungs?

2) Calculate the pressure inside a 375mL container filled with 37.2g of He at a temperature of -35°C.

3) Calculate the molar volume of COCl2 at 73°C and 1185 torr.

4) Chlorine gas, Cl2 and oxygen gas O2, are mixed in a container with a small hole in the side. The oxygen escapes from the container at a rate of 0.254mL/s. At what rate does Chlorine escape?
