In the process of underwater welding, a gas bubble is intentionally formed around the weld to protect it from water until it has cooled. To do so, a mixture of gas is used containing mole fractions of χH2=0.70 (70% hydrogen), χCO2=0.25 (25% carbon dioxide), and χCO=0.05 (5% carbon monoxide). If the total pressure on this gas bubble is 2.6 atm, what are the partial pressures of the three component gases (in atm)?
