How to calculate vapor pressure?
Here comes the Vapour pressure formula using Raoult's law, which explains how the vapour pressure of a liquid gets changed by the addition of a solute. P solution = (X solvent )( Po solvent ) X solvent = the mole fraction of the solvent in the solution. P solution = the vapour pressure of the solution.What is vapour pressure and formula?
Vapor Pressure: Vapor pressure is the partial pressure exerted by the vapor of a substance in the gaseous phase of a closed heterogeneous system at equilibrium with condensed phases (i.e. solid or liquid) of the substance present in the system.What is vapour pressure PDF?
At the normal boiling point of a liquid, the vapor pressure is equal to the standard atmospheric pressure defined as 1 atmosphere, 760 Torr, 101.325 kPa, or 14.69595 psi.
