IDEAL GAS LAW • What volume does 12. 5 g of argon gas at a pressure of 1. 05 atm and a temperature of 322 K occupy? Would the volume be different if the sample were 12. 5 g of helium (under identical conditions)?

Ideal Gas Laws • A sample of gas has an initial volume of 5. 6 L at a pressure of 735 mm. Hg. If the volume of the gas is increased to 9. 4 L, what is the pressure?

Ideal Gas Law • A 250. m. L aerosol can at 25 C and 1. 10 atm was thrown into an incinerator. When the temperature in the can reached 712 C, it exploded. What was the pressure in the can just before it exploded, assuming it reached the maximum pressure possible at that temperature (aka, assuming its an ideal gas)?

Ideal Gas Laws • An automobile tire has a maximum rating of 38. 0 psi (gauge rating). The tire is inflated while cold to a volume of 11. 8 L and a gauge pressure of 36. 0 psi (gauge rating) at a temperature of 12. 0 o. C. When the car is driven on a hot day, the tire warms up to 65. 0 o. C, and its volume expands to 12. 2 L. Does the pressure in the tire exceed its maximum rating? • *note gauge rating is the difference between the total pressure and atmospheric pressure. Assume the atmospheric pressure on these days is 14. 7 psi.
