Predict the mole fraction of b in the vapor produced when a mixture of 0. 70 mole fraction of a and 0. 30 mole fraction of b boils.

i think that the correct answer is

c. p equals 5,000 times, 0.3, to the power of the fraction m over 20

answer:

1,800

explanation:

4000 - 3,200 = 1,800

answer: I believe it's true. If you're going through a hard time such as a breakup, family problems etc anything... you can always go talk to someone you trust. Sure, life won't ever be easy at times neither will we always get what we want but U NEED TO HAVE HOPE. We'll go through things that we see unfair or that shouldn't be happening to us, but I hope that someday you recover from sadness and move along and be really happy. I promise you'll get over it sooner or later.

Hope that helps :) Hope we can still be friends too.
