3 paź 2024 · Calculation Formula. The vapor pressure of a solution is given by Raoult's Law: \[ VP{\text{solution}} = MF \times VP{\text{solvent}} \] Where: \( VP_{\text{solution}} \) is the vapor pressure of the solution, \( MF \) is the mole fraction of the solvent, \( VP_{\text{solvent}} \) is the vapor pressure of the pure solvent. Example Calculation

Find the vapor pressure of a solid or liquid at a given temperature by using the free vapor pressure calculator. Get the precise results in no time.
24 kwi 2021 · Calculate Vapor Pressure Using Raoult’s Law. Raoult’s law relates the vapor pressure of a solution (P solution) to the vapor pressure of the solvent (P solvent) and mole fraction of the solvent (X solvent):
Vapor Pressure Calculator. Blue fields allow input. The form below contains input fields, and read-only fields for output. Press <RETURN> or <TAB> to calculate. Accuracy: For many substances, vapor pressures are only poorly known; expect errors up to a few 10% of the vapor pressure value.
23 wrz 2024 · To find the vapor pressure at a given temperature, use the Clausius-Clapeyron equation: ln(P1/P2) = (ΔH vap /R)((1/T2) - (1/T1)). You could also use Raoult's Law to find the vapor pressure: P solution =P solvent X solvent .
