I know the equations, but can someone explain it better than Kaplan..what is it for and which equation is for what? Thanks!

Psolution = vapor pressure of component 1 + vapor pressure of component 2 + ....

Psolution = (P1 * X1) + (P2 * X2) + ...

where
P? is the vapor pressure of the pure component
X? is the mole fraction of the component in solution

As the number of components increases the vapor pressure of each component decreases because the mole fraction of each component decreases

Assumption: The chemical bond b/w two liquids = the bonding within the liquids

can you give me an example of a type of problem with these calculations?

There's a problem similar like this at the end of G Chem Achiever 1, I'll look for it when I get home & try to post it later
