Multiple Choice Identify the choice that best completes the statement or answers the question. 1. Indicate which aqueous solution has the highest vapor pressure. a. $0.1\mathrm{MKCl}$ d. $0.1{\mathrm{MMgCl}}_2$ b. $0.2{\mathrm{MNa}}_2{\mathrm{CO}}_3$ e. $0.2{\mathrm{MMgCl}}_2$ c. $0.2\mathrm{MNaCl}$ 2. Which graph best describes how the vapor pressure of a solution varies according to Raoult's law as a nonvolatile solute is added to a liquid? The vapor presstere of the solution is plotted on the $y$-axis, and the mole fraction of solvent is plotted on the $x$-axis. The origin $(0,0)$ is not necessarily located where the axes cross. a. I c. III b. II d. IV 3. The vapor pressure of an aqueous solution is found to be $24.9\mathrm{mm}\mathrm{Hg}$ at $25^{?}\mathrm{C}$. What is the mole fraction of solute in this solution? The vapor pressure of water is $25.756\mathrm{mm}\mathrm{Hg}$ at $25^{?}\mathrm{C}$. a. 0.967 d. 0.0344 b. 0.0332 e. 0.976 c. 1.03 4. A colligative property does not depend on a. the concentration of solute. b. the type of solvent. c. the volume of solution. d. whether a solute is a strong or weak electrolyte. e. the identity of the solute present.
