1. A sample of CO 2 with a pressure of 76.0 mm Hg in a volume of 0.200 L is compressed so that the new pressure of the gas is 90.0 mm Hg. What is the new volume of the gas? Assume that temperature is constant. 2. Suppose you have a sample of CO 2 in a gas-tight syringe. The gas volume is 38.0 mL at 25˚C. What is the final volume of the gas if you hold the syringe in your hand to raise its temperature to 40˚C? 3. You have a 34.0 L cylinder of helium at a pressure of 110 atm and a temperature of 43˚C. How many balloons can you fill, each with a volume of 26.0 L, on a day when the atmospheric pressure is 600 mm Hg and the temperature is 15˚C? 4. A hot air balloon is filled with 2000 grams of H2. If the temperature of the gas is 32˚C and its pressure is 800 mm Hg, what is the volume of the balloon? 5. A .306 gram sample of a gaseous compound has a pressure of 400 mm Hg in a volume of 225 mL at 27˚C. What is its molar mass? 6.
