1. A 100.0 ml flask containing nitrogen, N_2, at a pressure of 160. mmHg is emptied into a 100.0 mL flask of carbon dioxide, CO_2. The combined pressure of the two gases is 300. mmHg. What was the original pressure of the CO_2?

2. An air-filled balloon has a volume of 225 L at 0.94 atm and 25.0°C. Soon after, the pressure changes to 0.99 atm and the temperature changes to 0.0°C. What is the new volume of the balloon?

3. A discarded spray paint can contains only a small volume of the propellant gas at a pressure of 34,470 Pa. The volume of the can is 473.18 mL. If the can is run over by the garbage truck and flattened to a volume of 13.16 mL, what is the pressure in Pa assuming the can does not leak? The temperature of the gas does not change.

4. A tank of compressed CO_2, has a temperature of 23.6°C and a volume of 31.4 L. The CO_2 is completely transferred into a smaller tank that has a volume of 25.0 L. If the pressure in the small tank is the same as the pressure in the large tank, how much was the temperature of the gas changed?

5. What Is the density of a gas at STP if its density is 1.75 g/cm^3 at 110. kPa and 45.0°C? 

6. A storage tank contains 120. liters of oxygen at 147 °C and 6.0 atmospheres. Find the mass of the gas in the tank.

7. A cylinder-contains an equal number of moles of nitrogen gas and oxygen gas at 25°C. The container develops a small hole and the gases begin to leak out of the container. At the end of one hour, what are the relative amounts of each gas in the container? Is there still an equal amount of each? Explain. 

8. A particular tank can safely hold gas up to a pressure of 36.2 atm. When the tank contains 36.0 g of N_2 at 
25°C, the gas exerts a pressure of 12.7 atm. What is the highest temperature to which the gas sample can be safely heated?
