Estimate solution vapor pressure for ideal mixtures.
Solution Vapor Pressure (P_sol)
0.5000 atm
P_sol = χ_solvent × P°
Raoult's law states that the partial vapor pressure of each component in an ideal solution equals the vapor pressure of the pure component times its mole fraction.
Provide the pure solvent vapor pressure and the mole fraction of the solvent (0–1). The calculator shows the solution vapor pressure for ideal behaviour.
Pure solvent vapor pressure 1 atm, solvent mole fraction 0.8 → P_sol = 0.8 atm.
Q: Is non-ideal behaviour included? A: No — Raoult's law applies to ideal solutions. Q: Units? A: Pressure in atm.
