IN THE preface to the first edition of Chemical Engineering, Volume 4, we quoted the following paragraph written by Coulson and Richardson in their preface to the first edition of Chemical Engineering, Volume 1: We have introduced into each chapter a number of worked examples which we believe are essential to a proper understanding of the methods of treatment given in the text. It is very desirable for a student to understand a worked example before tackling fresh practical problems himself. Chemical Engineering problems require a numerical answer, and it is essential to become familiar with the different techniques so that the answer is obtained by systematic methods rather than by intuition.'

Let us consider that the mass of the solution is 100 grams In the case of Benzene: Mass of benzene = 30 grams molar mass of benzene = 78 N u m b e r o f m o l e s = W e i g h t i n g r a m s M o l e c u l a r w e i g h t Number of moles of benzene = 30 78 = 0.38 In the case of Carbon tetrachloride: mass of carbon tetrachloride = 70 molar mass of carbon tetrachloride = 154 N u m b e r o f m o l e s o f c a r b o n t e t r a c h l o r i d e = G i v e n m a s s o f c a r b o n t e t r a c h l o r i d e M o l e c u l a r m a s s o f c a r b o n t e t r a c h l o r i d e Number of moles of carbon tetrachloride = 70 154 = 0.45 Therefore, the total number of moles = 0.38+0.45 = 0.83 Now, M o l e f r a c t i o n o f b e n z e n e = N u m b e r o f m o l e s o f b e n z e n e N u m b e r o f m o l e s o f b e n z e n e + N u m b e r o f m o l e s o f c a r b o n t e t r a c h l o r i d e M o l e f r a c t i o n o f b e n z e n e = 0.38 0.38 + 0.45 = 0.461 Conclusion: Thus, the mole fraction of benzene is 0.461
