Description 1. Perform the conversions. 691.1 mmHg= atm 1.135 atm= Torr 650.5 kPa= atm 867.3 mmHg= Pa 2. The pressure of a sample of argon gas was increased from 1.86 atm to 6.70 atm at constant temperature. If the final volume of the argon sample was 11.1 L, what was the initial volume of the argon sample? Assume ideal behavior. ?= L 3. A sample of oxygen gas initially at 383 K was heated to 437 K. If the volume of the oxygen gas sample at 437 K is 738.8 mL,what was its volume at 383 K? ?= mL 4. A sample of xenon gas occupies a volume of 7.61 L at 441 K. If the pressure remains constant, at what temperature will this same xenon gas sample have a volume of 4.43 L? ?= K 5. An ideal gas in a sealed container has an initial volume of 2.60 L. At constant pressure, it is cooled to 17.00 ?C, where its final volume is 1.75 L. What was the initial temperature? ?1= ?C 6. A sample of an ideal gas has a volume of 2.30 L at 288 K and 1.11 atm. Calculate the pressure when the volume is 1.88 L and the temperature is 301 K. ?= atm 7. A gas?filled weather balloon has a volume of 58.0 L at ground level, where the pressure is 755 mmHg and the temperature is 22.0 ?C. After being released, the balloon rises to an altitude where the temperature is ?5.71 ?C and the pressure is 0.0702 atm.What is the weather balloon’s volume at the higher altitude? ?= L 8. A 3.53 mol sample of freon gas was placed in a balloon. Adding 3.50 mol of freon gas to the balloon increased its volume to 15.8 L
