1. A given amount of molecular oxygen gas is in a closed, expandable container. Assuming that the molecular oxygen acts as an ideal gas, answer the following questions.
a. What will happen to the volume if the temperature doubles and the pressure remains constant?
b. What will happen to the pressure if the volume is decreased by half and the temperature is doubled?
2. A sample of molecular nitrogen gas, N2, occupies 3.0 L at a pressure of 3.0 atm. What volume will it occupy when the pressure is changed to 0.50 atm and the temperature remains constant?
3. A 325 mL sample of air at 0.95 atm and 30.0oC, occupies what volume at 1.05 atm and 75.0 oC?
4. Molecular hydrogen gas was collected over water in a eudiometer at 25.0°C when the atmospheric pressure was 752 mm Hg. What was the pressure of the molecular hydrogen gas? (Water vapor pressure at 25.0°C is 23.756 mmHg)
