Answer:

0.5455

Explanation:

The moles of benzene in the process stream in 1 sec = 450 moles

The moles of toluene in the process stream in 1 sec = 375 moles

So, according to definition of mole fraction:

$Mole\ fraction\ of\ benzene=\frac {n_{benzene}}{n_{benzene}+n_{toluene}}$

Applying values as:

$Mole\ fraction\ of\ benzene=\frac {450}{450+375}$

Mole fraction of benzene in the process stream = 0.5455
