For each of the following gas law problems; (1) state the information given in the problem, (2) state what the problem is asking for, (3) specify which law (or equation) relates all of the variables involved int the problem, and (4) solve the problem. a. A syringe containing 8.76 mL of carbon dioxide gas initially at 25°C is placed into an ice bath. If the volume of the gas decreases to 2.92 mL, what is the final temperature (in °C) of the gas in the syringe assuming the pressure is held constant? b. A 2.50-L container holds nitrogen gas initially at a pressure of 1.75 atm. The gas is then allowed to expand, at a constant temperature, until it reaches a pressure of 1.00 atm. What is the new volume of the nitrogen gas? is the pressure (in atm) of the water vapor in the vessel? mass of the gas? c. A 355-mL vessel contains 0.500 moles of water vapor at 112°C. What d. The density of a particular gas at STP is 3.16 g/L. What is the molar e. A rigid container is filled with 173 Torr of air at 298K. The air inside the container is then heated to 453 TorT. What is the pressure of the air at this temperature? f. A cylinder with a movable piston contains 0.233 moles of ammonia gas (NH3) and has a volume of 315 mL. What is the volume after an additional 0.254 moles of ammonia is added to cylinder while the pressure and temperature is held constant?
