Hello.  Is there a way to calculate the actual concentration of a solution containing a semi-volatile compound?  The only information I have is boiling point.
Thanks.

well, first u have to determine what the compaund is...then use a Gas Chromatography to analyze it...

I actually do know what the compounds are.  I have two alcohols that have varying degress of volatility, I assume.  I am using them as inhibitors of bacterial growth and in order to do a complete comparison, I need to determine what their actual concentrations are, i.e., what percent stays in solution and which is in gas phase.  There are no published Henry's Law constants, thus I was hoping to determine this using only the boiling points.  Any suggestions?
