2. The reaction above is used to generate nitrogen gas in an automobile airbag. What mass of NaN3 is required to inflat a 20L airbag to a pressure of 1.25 atm at 270C.
Diver A is 64 ft below the surface of the water ( the pressure here is approximately 3.0 atm) and has 750 ml of air in his lungs when he sees a shark. Panicking , he returns directly to the surface without breathing out. What is the volume of his lungs when he reaches the surface?

3. A sample of nitrogen gas in a flask is heated from 27ºC to 150ºC
A sample of nitrogen gas in a flask is heated from 27ºC to 150ºC. If the original sample of gas is at a pressure of 1520 torr, what is the pressure in the final sample (in atm)?
