Vapor pressure of ethylene glycol solution

What is the vapor pressure of a 32.0% solution of ethylene glycol in water? The vapor pressure of pure water at 100 C is 760 mm Hg. You need to go from percent to grams. It is convenient to assume you have 100 grams of water. Then we can go from grams of water to moles of water and grams of ethylene glycol to moles of ethylene glycol. With these two mole quantities, we can calculate the mole fraction of water and apply Raoult’s vapor pressure lowering formula to determine the vapor pressure of the solution.
