We’re being asked to solve for the final pressure in terms of the original pressures of helium and neon

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

Pgas=χgasPtotal

where: 

χGas = mole fraction of the gas

Ptotal = total pressure of the gas mixture


Mole fraction can be calculated using the equation shown below:

χGas 1=moles Gas 1Total Moles


Calculate the mole fraction of each gas:
