1 13.10 Day Seven

2 Vapor Pressure Lowering
PActual = PsolventXsolvent Psolvent = Vapor Pressure of Solvent Xsolvent = mole fraction of solvent What is the vapor pressure of a solution at 70OC if 100 grams of water has dissolved 200 grams of C12H22O11?

3 Osmotic Pressure Happens when a solvent moves through a membrane in an attempt to balance the concentration Movement of the solvent creates pressure The more solute, the more water moving, the more osmotic pressure

4 Osmotic Pressure Remember from last chapter the ideal gas equation.
P= nRT/ V We can rewrite this as the following ∏ = MRT
