1) A holding vessel contains a sample of gas at 17.4 atm, 7.70 L, and 291 K. If the vessel shifts to maintain the pressure at 30.1 atm and 323.2 K, what will the new volume of the gas be?
2) How much faster would He gas effuse than Ar? Record your answer to 2 decimal spaces.
3) A laboratory group measures an excess of a volatile liquid. They add this to an empty flask with a volume of 290 mL. They heat the sample to 80.2 degrees Celcius until all the liquid is vaporized. The pressure in the lab is 0.987 atm. If 0.238 grams of volatile liquid were left in the flask, what was the molar mass of the compound?
4) How many grams of water vapor would be required to occupy a 744 mL flask at 1.06 atm and 85.8 degrees Celcius?
