I have a mix of gas law problems. Can anyone help me with these?

1.A sample of carbon dioxide gas occupies 1.55 L at -17.6oC and 556 mm Hg. If the volume of the gas is changed to 2.78 L at 779 mm Hg, what is the final Kelvin temperature? 2. A sample of ozone gas occupies 231 mL at 3.92 atm and 0oC. If the volume of the gas is 619 mL at 32.9oC, what is the pressure? Enter mm... show more 1.A sample of carbon dioxide gas occupies 1.55 L at -17.6oC and 556 mm Hg. If the volume of the gas is changed to 2.78 L at 779 mm Hg, what is the final Kelvin temperature?

2. A sample of ozone gas occupies 231 mL at 3.92 atm and 0oC. If the volume of the gas is 619 mL at 32.9oC, what is the pressure? Enter mm for unit.

3. The pressure of sulfur trioxide gas at 29.6oC increases from 0.49 atm to 1.21 atm. What is the final Kelvin temperature if the volume remains constant?

4.A sample of propane gas occupies 641 mL at -65.7oC and 750 mm Hg. What is the final volume at 37oC and 750 mm Hg.
