Given the set of experimental VLE data for a CO₂ /toluene mixture at T = 80°C of W. Morris and M. Donohue, “Vapor–liquid equilibria in mixtures containing carbon dioxide, toluene, and i-methylnaphthalene,” J. Chem. Eng. Data, 30, (3), 259–263, 1985,

estimate the Henry’s constant. Use the result to calculate the bubble pressure at 400 K for a molar concentration of CO₂ in the liquid phase of 0.015.
