1. An oxygen sample contains volume of 6.00 L at 25oC and 900. torr. How many molecules does this sample contain?
0.291 0.502 2.46*10^23 1.75*10^23 6.02*10^23

2. A gas is heated from -10.0oC to 60oC and the volume is increased from 1.0 L to 6.0 L. If the initial pressure is 0.5 atm, what is the final pressure?
0.10 atm 0.11 atm 0.12 atm 0.25 atm 0.50 atm

3. Body temperature is around 308oK. What volume of air at 298oK must a person with a lung capacity of 2.5 L breath in to fill the lungs?
2.58 L 0.00811 L 2.42 L 4.26 L None of the above

4. If you have a gas taking 14.0 L at 800. torr and 26oF, calculate the volume of the gas at 40oC and 2 atm.
