A gaseous mixture is made 0.450 moles of Neon and 0.250 moles of Argon. The mixture is at 35.5 Celsius and in a container that has a volume of 18.5 Liters. Solve for the partial pressure of Argon using two different methods (note you should get the same answer for both methods):
Method 1
Solve for the total moles, then the total pressure of the mixture using the Ideal Gas Law. Next find the mole fraction of Argon and solve for partial pressure of Argon.
Method 2
Place the moles of Argon into the Ideal Gas Law and directly solve for the partial pressure of Argon.
Would you expect the partial pressure of Neon to be greater or less than Argon?
