1. How many cubic centimeters of carbon dioxide gas at 3.50 atmosphere of pressure are required to inflate a balloon that is 850. cm3 at 2.50 atmospheres? 2. A balloon filled with carbon dioxide & helium has a total pressure of 564.2 kPa. It was filled with carbon dioxide at a partial pressure of 456.9 kPa. What was the partial pressure of helium gas in the balloon?

3. A sample of an unknown gas exerts a pressure of 0.940 atm in a 452 mL container at 23.0°C. Calculate the moles of the gas?

4. The pressure of 6.24 L of a gas is increased from 25.0 kPa to 55.0 kPa. What is the new volume?

5. The volume (in L) that would be occupied by 5.00 moles of O2 at STP is.

6. Given the following unbalanced equation:CH4(g) + O2(g)  CO2 (g) + H2O(g)If you had 4.00 mol of CH4, how many L of H2Owould be produced at STP?
