What is partial pressure?

Partial pressure is the pressure that would be exerted by one of the gases in a mixture if it occupied the same volume on its own.

How to Calculate Partial Pressure (using Raoult's Law)?

Partial Pressure (using Raoult's Law) calculator uses Vapor Pressure of component A=Mole fraction of component A in liquid phase*Vapor Pressure of pure component A to calculate the Vapor Pressure of component A, Partial Pressure (using Raoult's Law) calculates the partial pressure of a given component in a mixture when the component's mole fraction in the liquid phase and its pure vapor pressure is known. Vapor Pressure of component A and is denoted by PA symbol.

FAQ

What is Partial Pressure (using Raoult's Law)?
Partial Pressure (using Raoult's Law) calculates the partial pressure of a given component in a mixture when the component's mole fraction in the liquid phase and its pure vapor pressure is known and is represented as PA=xA<*PAo or Vapor Pressure of component A=Mole fraction of component A in liquid phase*Vapor Pressure of pure component A. Vapor Pressure of pure component A is that pressure exerted by liquid or solid molecules of only A in a closed system at which they are in equilibrium with the vapor phase. This pressure also corresponds to the boiling point of component A and The mole fraction of component A in liquid phase refers to the mole fraction of component A in the liquid phase.
How to calculate Partial Pressure (using Raoult's Law)?
Partial Pressure (using Raoult's Law) calculates the partial pressure of a given component in a mixture when the component's mole fraction in the liquid phase and its pure vapor pressure is known is calculated using Vapor Pressure of component A=Mole fraction of component A in liquid phase*Vapor Pressure of pure component A. To calculate Partial Pressure (using Raoult's Law), you need Vapor Pressure of pure component A (PAo) and Mole fraction of component A in liquid phase (xA<). With our tool, you need to enter the respective value for Vapor Pressure of pure component A and Mole fraction of component A in liquid phase and hit the calculate button. You can also select the units (if any) for Input(s) and the Output as well.
