Question 1

The vapor pressure of water at 25.0°C is 23.8 torr. Determine the mass of glucose (molar mass = 180 g/mol) needed to add to 500.0 g of water to change the vapor pressure to 23.1 torr.

◦ 15.2 g
◦ 151 g
◦ 126 g
◦ 6.29 kg
◦ 185 g

Question 2

The vapor pressure of water at 90°C is 0.692 atm. What is the vapor pressure (in atm) of a solution made by dissolving 3.68 mole(s) of CsF(s) in 1.00 kg of water? Assume that Raoult's law applies.

◦ 0.649 atm
◦ 0.784 atm
◦ 0.611 atm
◦ 0.692 atm
◦ none of these are correct
