We’re being asked to **calculate the total pressure** of a gas mixture containing **CO, Ar, and H _{2}**.

Recall that the ** partial pressure of a gas (P_{Gas})** in a mixture is given by:

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

where:

**χ**** _{Gas}** = mole fraction of the gas

**P _{total}** = total pressure of the gas mixture

###### Problem Details

A gas mixture contains CO, Ar and H _{2}. What is the total pressure of the mixture, if the mole fraction of H_{2} is 0.350 and the pressure of H _{2} is 0.480 atm?
