Problem: A mixture of 8.1 g CH4 and 8.1 g Xe is placed in a container and the total pressure is found to be 0.45 atm .Find the partial pressure of CH4.

FREE Expert Solution

We’re being asked to calculate the partial pressure of CH4 in a mixture of Xe and CH4


Recall that the partial pressure of a gas (PGas) in a mixture is given by:


Pgas=XgasPtotal


where χGas = mole fraction of the gas and Ptotal = total pressure of the gas mixture


The mole fraction of the gas is then given by:

Xgas=mole gastotal moles
