Homework Statement

What is the capor pressure of a solution containing .15 mol of glucose (C6H12O6) and 1.65 mol of water at a temperature of 60.0C? the vapor pressure of pure water at this temperature is 149.38 torr

Homework Equations

Ralout's law?

P=PoX

The Attempt at a Solution

im guessing that the P on the left side of the eqn is is VP of pure water(149.38)

im not sure how to get x there is some formula like nsolute/(nsolute + nsolvent)


thanks

Using formula like the one you have listed, just remember you are looking for molar fraction of solvent, not solute.
