What is Vapour pressure?

Vapour pressure is the pressure exerted by a vapour when the vapour is in equilibrium with the liquid or solid form, or both, of the same substance i.e., when conditions are such that the substance can exist in both or in all three phases. It is a measure of the tendency of a material to change into the gaseous or vapour state, and it increases with temperature. The vapor pressure of any substance increases non-linearly with temperature. With any incremental increase in that temperature, the vapor pressure becomes sufficient to overcome atmospheric pressure and lift the liquid to form vapor bubbles inside the bulk of the substance and is measured in the standard units of pressure.

How to Calculate Vapour Pressure?

Vapour Pressure calculator uses Vapour Pressure of Solution=Mole Fraction of Solvent*Vapour Pressure of Solvent to calculate the Vapour Pressure of Solution, Vapour Pressure of Solution is the pressure of the vapor which is formed after a solid get dissolves into the liquid. Vapour Pressure of Solution and is denoted by Psolution symbol.

How to calculate Vapour Pressure using this online calculator? To use this online calculator for Vapour Pressure, enter Mole Fraction of Solvent (χsolvent) and Vapour Pressure of Solvent (Posolvent) and hit the calculate button. Here is how the Vapour Pressure calculation can be explained with given input values -> 25470 = 0.9*28300.

FAQ

What is Vapour Pressure?
Vapour Pressure of Solution is the pressure of the vapor which is formed after a solid get dissolves into the liquid and is represented as Psolution=χsolvent*Posolvent or Vapour Pressure of Solution=Mole Fraction of Solvent*Vapour Pressure of Solvent. Mole Fraction of Solvent is the concentration of solvent in the solution and Vapour Pressure of Solvent is the pressure of the vapour which is formed before a solid get dissolves into the liquid.
How to calculate Vapour Pressure?
Vapour Pressure of Solution is the pressure of the vapor which is formed after a solid get dissolves into the liquid is calculated using Vapour Pressure of Solution=Mole Fraction of Solvent*Vapour Pressure of Solvent. To calculate Vapour Pressure, you need Mole Fraction of Solvent (χsolvent) and Vapour Pressure of Solvent (Posolvent). With our tool, you need to enter the respective value for Mole Fraction of Solvent and Vapour Pressure of Solvent and hit the calculate button. You can also select the units (if any) for Input(s) and the Output as well.
