The molar ratios of toluene to cyclohexane were calculated for each prepared solution was calculated. Values were attained using the curve area and heights respectively. The molar ratio was calculated from the area of the respective curves as follows. The average area of the curve for a 1 sample of pure cyclohexane was calculated as in the table above. The number of moles of cyclohexane in 1 was calculated using given values for the density of cyclohexane and the molecular weight of cyclohexane: The number of moles of cyclohexane in each of the binary systems can be calculated using the following relation: Where is the area of the cyclohexane curve determined by chromatograph analysis and is the averaged area of the three reference samples of pure cyclohexane. This calculation was also carried out for the toluene in sample. For these calculations, the density of toluene was taken to be 0.8669 g/mL and the molecular weight of toluene was taken to be 92.1381 g/mol. The molar ratio of toluene in the solutions was then calculated from the relation: Where is the molar ratio of toluene and and are the respective number of moles previously calculated for the vapour and liquid phases of each system. Then the boiling point temperature was plotted as a function of the molar ratio of toluene in the vapour and liquid phases respectively. The molar ratios of toluene to cyclohexane can also be calculated using the height of their resultant curves. The boiling point was subsequently plotted as a function of the molar ratio of toluene attained using the adjusted peak height for toluene, , in the relation as follows:
