1) The trapped gas in a closed-end tube occupies 24.8 cm 3 at 1.12 atm. If you increase the Pressure on the trapped gas in the tube to 2.64 atm, and keep the Temperature constant, what is the new Volume of the gas? 1) A 1-liter steel tank is fitted with a safety valve that opens if the internal Pressure exceeds 1.00x10 3 torr. The tank is filled with He at 23°C and 0.991 atm and placed in boiling water at exactly 100°C. Will the safety valve open? 1) A scale model of a blimp rises when it is filled with He to a volume of 55.0 dm 3 . When 1.10 mol of He is added to the blimp, the Volume = 26.2 dm 3 . How many more grams of He must be added to make it rise? 1) A steel tank has a Volume of 438 L and is filled with 0.885 kg of O 2 . Calculate the Pressure of the O 2 at 21°C.

5) Calculate the density and the number of molecules/liter of CO 2 at STP and room temperature (20°C). 1) Dumas apparatus data: Volume of flask = 213 mL, Temperature of the water = 100.0°C, atmospheric Pressure = 754 torr, mass of flask and gas = 78.416 g, mass of flask = 77.834 g. Using this data, calculate the molar mass of
