Question

The solubility constant for CO₂ in water at 25 $LaTeX: ^\circ$ ∘C is 3.40 x 10^-2 M/atm. The solubility of CO₂ is 34.164 mM in water that is exposed to a gas mixture in which the mole fraction of CO₂ is 0.78. What is the total pressure of this gas mixture? Express your answer in units of atmospheres using at least three significant figures.
