A 1.0 L ball containing Ar at 5 atm is connected to a 10.0 L ball containing N2 at 2atm.

A)Calculate the partial pressures and mole fractions of Ar and N2 after the valve is opened and the gases are allowed to mix (they fill the balls on both sides).

My answers:
P argon = 0.455 atm
P nitrogen = 1.82 atm
X argon = 0.2
X nitrogen= 0.8

B) Total pressure?

My answer: 2.275 atm

C) If we added enough argon to raise its mole fraction to 0.5 in the mixture, what would the new total pressure be?

My answer: 4.55 atm
