Unformatted text preview: 7. A mixture of gases contains 0.75 mol N 2 , 0.30 mol O 2 and 0.15 mol CO 2 . If the total pressure is 1.56 atm, what is the partial pressure of each component? 8. a) Calculate the partial pressure of gases in a mixture containing 4.5g each of CO 2 , N 2 , and O 2 . b) Calculate the total pressure of the system in a 5L flask at 25 o C. 9. a) Calculate the density of NO 2 gas at 0.85 atm and 45 o C. b) Calculate the molar mass of a gas if 2.5g occupies 0.875L at 685 torr and 40 o C. 10. What is the total P exerted by a mixture of 2g H 2 and 8g N 2 at 273K in a 10L vessel?...
