Assuming ideal behavior, calculate the change in vapor pressure upon the addition of 0. 500 mole fraction toluene, calculate the total vapor pressure and the mole fraction of toluene in the Dec 2, 2022 · Benzene boils at 81 °C and toluene boils at 110 °C. Temperature Step=. 01 In Psat = 14. Calculate the mole fraction of water (the solvent). 4 mmHg, respectively. where PA P A is the vapor pressure of component A of the solution (in this case the solvent), XA is the mole fraction of A in solution, and P0A P A 0 is the vapor pressure of pure A. bi er fr rs bi sw oz ye si nb
