The boiling points for pure water and pure toluene are 100°C and 110.6°C respectively. Toluene and water are completely immiscible in each other. A well agitated equimolar mixture of toluene and water are prepared. The temperature at which the above mixture will exert a pressure of one standard atm. is

Stoichiometry
Raoult's law states that 'the equilibrium vapor pressure that is exerted by a component in a solution is proportional to the mole fraction of that component'. This generalisation is based on the assumption that the

Component molecules are non-polar and no chemical combination or molecular association between unlike molecules takes place in the formation of the solution

All of these

Sizes of the component molecules are approximately equal

Attractive forces between like and unlike molecules are approximately equal
