Question
Chapter 14, Problem 13E
Interpretation Introduction
Interpretation:
The reason for the mass percentage of ethanol in anaqueous solution to be less than the volume percentage of ethanol in the same solution needs to be explained. The application to all aqueous solutions and all ethanol solutions needs to be explained.
Concept introduction:
Density of a sample can be defined as mass of the sample divided by its volume. The density of water is close to 1.0 g mL-1,while the density of ethanol is about 0.8 g mL-1

- 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.)arrow_forward6-111 As noted in Section 6-8C, the amount of external pressure that must be applied to a more concentrated solution to stop the passage of solvent molecules across a semipermeable membrane is known as the osmotic pressure The osmotic pressure obeys a law similar in form to the ideal gas law (discussed in Section 5-4), where Substituting for pressure and solving for osmotic pressures gives the following equation: RT MRT, where M is the concentration or molarity of the solution.
