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_a = Mole fraction of component A in liquid phase*Vapor Pressure of pure component A. The mole fraction of component A in liquid phase refers to the mole fraction of component A in the liquid phase and 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.
How to calculate Partial Pressure (using Raoult's Law)?
