7. Which one of the following relationships when graphed gives a straight line for helium gas? I. V versus T at constant pressure for a constant mass II. P versus n at constant volume and temperature III. V versus n at constant temperature and pressure IV. P versus V at constant temperature and moles of gas 8. A high altitude balloon is filled with 1.41 x 10* L of helium at 21°C and 745 torr. What is the volume (L) of the balloon at 20 Km where the temperature is -48°C and 63.1 torr? 9. A scuba diver inhales a lung-full (350 mL) of air at a depth of 33 ft where the pressure is approximately 2.0 atm and the water temperature is 18°C. If the diver holds her breath (not a good idea!!), what volume will the same amount of air occupy at sea level where the pressure is approximately 1.0 atm and the air temperature is 35°C? 10. Hydrogen can be made in the by the following equation: C(s) + H20(g) → H2(g) + CO(g) If you begin with 250. L of gaseous water at 120° C and 2.0 atm pressure, how many grams of H2 can be made? What volume of H2 is produced? What volume of H2 is produced at STP?

Gas Law Practice (IC-6) 1. At what temperature will 5.00 g of Cl2 exert a pressure of 900. torr at a volume of 750.mL? 2. What pressure will be exerted by 25 g of CO2 at a temperature of 25 °C and a volume of 500.mL? 3. Find the number of grams of CO2 that exert a pressure of 785 torrs at a volume of 32.5 L and a temperature of 32 °C 4. An elemental gas has a mass of 10.3 g. If the volume is 58.4 L and the pressure is 758 torrs at a temperature of 2.5°C, what is the molar mass of the gas? 5. A flask of unknown volume containing a gas at 4.0 atm is attached to a 5.0 L evacuated flask. The air from the first flask is allowed to expand into the second flask and the observed final pressure is 2.5 atm. What is the volume of the first flask (L)? 6. A 300 mL sample of helium at 127°C is cooled to 150°K. What is the volume (mL) if the pressure is kept constant?
