We’re being asked to calculate the total pressure of a gas mixture containing CO, Ar, and H2

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

$\overline{){{\mathbf{P}}}_{{\mathbf{gas}}}{\mathbf{=}}{{\mathbf{\chi }}}_{{\mathbf{gas}}}{{\mathbf{P}}}_{{\mathbf{total}}}}$

where:

χGas = mole fraction of the gas

Ptotal = total pressure of the gas mixture ###### Problem Details
