The total pressure of the mixture is the sum of the partial pressures of each gas. The partial pressure of a gas is the pressure it would exert if it occupied the entire volume alone. The mole fraction of a gas is the ratio of the number of moles of that gas to the total number of moles of all gases in the mixture. The partial pressure of a gas is equal to the mole fraction of that gas multiplied by the total pressure of the mixture.In this case, the mole fraction of H₂ is 0.35 and the pressure of H₂ is 0.58 bar. Therefore, the partial pressure of H₂ is 0.35 * 0.58 bar = 0.20 bar. The total pressure of the mixture is the sum of the partial pressures of CO, Ar, and H₂. Therefore, the total pressure of the mixture is 0.20 bar + 0.20 bar + 0.58 bar = 1.7 bar.
