Question 1

A solution contains 15.5 g of NaOH dissolved in water to give a total mass of 125.0 g. What is the molality of the solution?

◦ 0.00310 m
◦ 0.124 m
◦ 3.54 m
◦ 3.10 m
◦ 124 m

Question 2

A solution is made by adding 0.100 mole of ethyl ether to 0.401 mole of ethyl alcohol. If the vapor pressure of ethyl ether and ethyl alcohol at 20°C are 375 torr and 20.0 torr, respectively, the vapor pressure of the solution at 20°C (assuming ideal behavior) is:

◦ 90.9 torr
◦ 304 torr
◦ 58.8 torr
