Consider a solution made by massing 8.3 g of a nonvolatile solute (molar mass = 68.51 g/mol) and then adding water to the 100-mL mark on a volumetric flask. The solution density is 1.03 g/mL at a temperature of 30.8°C. The vapor pressure o water at this temperature is 33.3 torr. The freeing point depression constant fo water is 1.86 K/molal. Part 1- Answer ALL of these. (a) Compute the mole fraction of solute in the solution. (b) Compute the mole fraction of water in the solution. (c) Compute the molarity of the solution. (d) Compute the molality of the solution.

The vapor pressure of an aqueous solution of urea. CH4N2O, is 291.2 mmHg at a measured temperature. The vapor pressure of pure water at that temperature is 355.1 mmHg. Calculate the mole fraction of each component.
Which solute has the greatest effect on the boiling pointof 1.00 kg of water: 50.0 g of strontium chloride (SrCl2) or 150.0 g of carbon tetrachloride (CCl4) ? Justify youranswer.
Consider 2 vapor pressure curves A and B. They are the vapor pressure curves of pure benzene and a contaminated solution of benzene with a nonvolatile solute. (a) Which graph shows the vapor pressure curve for pure benzene? (b) What is the boiling point of the contaminated benzene solution? (c) Estimate the molality of the contaminated solution (k b=2.53C/m).
Sodium chloride (NaCl) is commonly used to melt ice on roads during the winter. Calcium chloride (CaCl2) is sometimes used for this purpose too. Let us compare the effectiveness of equal masses of these two compounds in lowering the freezing point of water, by calculating the freezing point depression of solutions containing 200. g of each salt in 1.00 kg of water. (An advantage of CaCl2 is that it acts more quickly because it is hygroscopic, that is. it absorbs moisture from the air to give a solution and begin the process. A disadvantage is that this compound is more costly.)
Define the terms in Raoults law. Figure 10-9 illustrates the net transfer of water molecules from pure water to an aqueous solution of a nonvolatile solute. Explain why eventually all of the water from the beaker of pure water will transfer to the aqueous solution. If the experiment illustrated in Fig. 10-9 was performed using a volatile solute, what would happen? How do you calculate the total vapor pressure when both the solute and solvent are volatile?
