Honors Gas Laws Homework

1.) A 5.25 L sample of air has a pressure of 700 torr at 30 °C. What volume will the gas occupy at 900 torr and 80 °C? 2.) A quantity of nitrogen gas occupies a volume of 8.3 L at STP. How many moles are present? What would the mass be? 3.) A gas contains a mixture of two gases. The mole fraction of Gas B is 0.25 and has a partial pressure of 0.46 atm. What is the total pressure in the container and the partial pressure of argon? 4.) A balloon is filled with carbon dioxide gas and another is filled with ammonia gas. How much faster will the ammonia-filled balloon deflate? 5.) The gas has a density of 1.95 g at 25˚C and 103 kPa. Determine the molar mass of the gas.
