VAPOR PRESSURE PROBLEM IS KILLING ME! Thanks for any input
« on: July 13, 2012, 08:11:55 PM »
Glycerol, HOCH2CHOHCH2OH, is a non-volatile water soluble material.  It's density is 1.25g/ml.  Predict the vapor pressure of a solution of 2.60x10^2ml of glycerol, in 375ml of water, at the normal boiling point of water.

I would love to have someone explain to me how to do this.  Thank you in advance if you can help

I get the molarity of the glycerol as 3.53 M but dont know how to move forward with getting waters and moving forward from there.  I am new to these problems.  I am in genchem 2 in summer school and of course the pace is faster than normal, so I am trying to stay ahead of the curve in getting this stuff understood ahead of time.

Sorry, when I read the title, all I could think about was this:

To help with your question, though, do you know what Raoult's Law says?
