1000kg/h of a mixture of benzene and toluene that contain 50%w/w benzene by mass are separated by distillation into two fraction the mass flow of benzene in the product top stream is 450kg b/h and that of toluene in gotten steam is 475kg t/h find the composition of each steam in mass mole and volume fraction then calculate the %of each component in each steam
