Question

Can anyone help me with chemistry?

Answer 1

I think there is a study group for it ;)

Answer 2

which topic are you expecting help in?

Answer 3

There is, and I have already asked there, but no one is responding.
I need help finding mole fractions.

Answer 4

Here, I'll post the question so you cam see what I'm talking about.
At a given temperature, you have a mixture of benzene (vapor pressure of pure benzene = 745 torr) and toluene (vapor pressure of pure toluene = 290. torr). The mole fraction of benzene in the solution is 0.590. Assuming ideal behavior, calculate the mole fraction of toluene in the vapor above the solution.
