Chem 1075 Take-Home Problem Set #6 Gases Name___________________________
1. Convert 880mmHg to atm:
2. Convert 0.987 atm to torr:
3. Convert 45oC to K:
4. Consider a piston-like container where one side can move up and down. A fixed amount of gas is in the
container and a heavy weight is placed on the movable side. If the weight exerts 7/4ths times the original
pressure on the gas, how is the volume affected?
5. If a fixed amount of gas at 1.05 atm is cooled from 33oC to 88oC, what is the new pressure?
6. If 50.0mL of gas at 0.995 atm and 28oC is compressed to a volume of 25.0mL at a temperature of 18oC,
what is the final pressure?
7. If 6.42 moles of gas are in a steel cylinder (fixed volume) at a pressure of 4400 mmHg and an additional
4.50 moles of gas are pumped into the cylinder, what would the new pressure be?
8. What does STP represent? What are its values? (See Ch. 9 Slide 17)
