Raoult’s Law Problem:

Your turn: Assume the solution (from earlier)

containing 62.1 g of glycol in 250. g of water is

“ideal”. What is the vapor pressure of water over the

solution at 30 oC? (The VP of pure H2O is 31.8 mm

Hg)

Solution Hints: (1) Calc. each X (glycol, then water)

Rem: Xglycol + X water = 1

(2) VPoH2O = 31.8 mm

(3) calc. VP of water over the soln.
