6. Pressurized carbon dioxide inflators can be used to inflate a bicycle tire that has gone flat. These inflators use metal cartridges that contain 16.9 g CO. At 298K, to what pressure (in psi) on the pressure gauge can the carbon dioxide in the cartridge inflate a 3.45 L mountain bike tire? (Note: the gauge pressure is the difference between the total pressure and the atmospheric pressure, which for this problem is 14.7 psl/1 atm). 7. What is the pressure...
