Find the Molar percentage
A solution contains 55% benzene (molecular weight 78 , vapour pressrire at 373K(100C ) =178.65kPa ), 28% toluene (molecular weight 92 , vapour pressure at 373K=74.66kPa ) and 17% xylene (molecular weight 106 , vapour pressure =2.8kPa, by mole at 300K(100C)). The vapours are in contact with the solution. Calculate the total pressure of the vapours in a mixture. Also find the molar percentage composition of toluene and xylene
