Question

please solve this question step by step​

Answer 1

Answer:

2/3

Explanation:

first of all

ps=PB+PT

here ps means pressure of solution

we know

Ps= p°BXB+P°TXT

where XB and XT are molar ratio of benzene and toulene respectively

now Ps = 100×1/3+25×2/3

by solving this we will get,

Ps =50

now we have to find molar fraction of benzene in vapour phase that is YB

so , YB= P°B XB/ps

then 100/3/50

then u will get the answer 2/3

Note = here the sign B and T represents benzene and toulene respectively.

hope it will help u
