4 L of oxygen at a pressure of 400 Kpa and 1L of nitrogen at 200 Kpa were introduced in to 2 L vessel.
(A)What is the total pressure of the gases in the vessel.
(B)What is the mole fraction of each gas?
Use P1V1 = P2V2 to convert each gas from starting conditions to ending conditions in the 2L container.
a. Ptotal = pO2 + pN2.
b. XO2 = pO2/Ptotal
and XN2 = pN2/Ptotal.
