moles biphenyl = grams/molar mass
moles benzene = grams/molar mass
mol fraction benzene = Xbenzene = mol benzene/total moles.
partial pressure benzene = Xbenzene*Pnormal v.p.
I did what you said and didn't get the correct answer :(
Post your work and I'll try to find your error.
Can someone confirm the answer for this. I worked it out and got an answer of 85.5 torr. Is this right? Can someone please put the answer to this so I can check. Thanks. That would be helpful.
I worked it and obtained 86.9 torr which is close to your number but not quite the same. I used 154 for the molar mass of biphenyl and I used 78 for the molar mass of benzene.
If you will post your work I'll look at it. Please make a new post of it--this one is getting a little far from the front page.
