The weight percentage of toluene and xylene’in this mixture is 40 %- and 60%, respectively. Calculate the moles fraction of toluene and xylene ‘in this stream. a7 ie Question'ay” a Two engineers calculate the average molecular weight of a gas mixture containing oxygen and other gases. One of them uses the correct molecular weight of 32. for oxygen and determines the ndlecufar weight as 39.2. The other uses an incorrect value of_16. and finds out that the average molecular weight as 32.8. This is the only error. in his calculations. What is the percentage of oxygen.in the mixture expressed as mol %.
