A sealed glass container contains partial pressures of 0.24 atm O_2, 0.45 atm CO

Question

A sealed glass container contains partial pressures of 0.24 atm O_2, 0.45 atm CO_2, atm N_2, and 0.46 atm H_2 gas in a 3.5. L container at 30.5 degree C. What is the total pressure exerted on the walls on the container? a. 0.64 atm b. 0.51 atm c. 1902 atm d. 6.27 atm e. 1.79 atm A mixture of 5.00 moles of neon and 3.00 moles of nitrogen occupy a volume of 36.0 L ir. a vessel where the total pressure is 6.00 atm. The partial pressure of the neon in the container is a. 0.833 atm b. 43.2 atm c. 3.75 atm

Explanation / Answer

22. Total pressure   = Sum of partial pressure of all component

                       P        = PO2 + PCO2+ PN2+ PH2

                                  = 0.24 + 0.45 + 0.64 + 0.46 = 1.79atm

23. no of moles of He n He = 5

    no of moles of N2 n N2    = 3

mole fraction of He XHe   = nHe/n He + n N2

                                           = 5/5 +3    = 5/8   = 0.625

Total pressure                    = 6 atm

partial pressure of He PHe   = mole fraction of He * total pressure

                                                = 0.625*6   = 3.75atm
