5. A 50. 0-L steel tank contains 186 mol N2 and 145 mol O2 at 24oC
A 50.0-L steel tank contains 186 mol N2 and 145 mol O2 at 24oC. What is the partial pressure of each gas in the tank? What is the total pressure in the tank?

6. Consider a sample of gas at 2.00 atm in a 35.0-L container at 25.0oC. You transfer all of the gas to a 70.0-L container and you heat the gas to 50.0oC.
Determine the new pressure of the gas.

7. Consider a sample of gas at 5. 40 atm in a 1
Consider a sample of gas at 5.40 atm in a 1.00-L rigid container at 40.0oC. You heat the gas to 80.0oC. What happens?
Solve for the new condition.
