***{When I word something poorly in a post, I don't usually bother to
with a correction, provided that it is apparent from context that the
underlying thought was correct. However, the last sentence quoted above
sucks sooooooo much that I can't let it pass, even though my use of the
concept in the context was correct. The proper wording would be:

"Moreover, it is a simple, linear relationship known as Raolt's law--to
wit: the vapor pressure of a solution containing dissolved minerals is
directly proportional to the mole fraction of the solvent in the
solution, where "mole fraction" is simply the number of moles of the
solvent (water, in this case) divided by the total number of moles in
the solution."

So there you have it. :-)
