$(0\mathrm{.}5$ pts$.)$ Raoult's Law: P$.20-25$

Compute the vapor pressure above a solution containing $120\mathrm{.}12g$ of the nonvolatile solute NaCl in $400\mathrm{.}00$ grams of the volatile solvent water given that the vapor pressure of pure water at $25$degC is $23\mathrm{.}76mmHg.$

$2.(0\mathrm{.}5$ pts$.)$ Raoult's Law P$.21,26-27.$

A solution contains $3\mathrm{.}475$ moles of $A,2\mathrm{.}515$molB, and $1\mathrm{.}215$molC. The vapor pressures of pure $A,B,$ and $C$ are respectively $100\mathrm{.}00mmHg\mathrm{.}50\mathrm{.}00mmHg,$ and $25\mathrm{.}00mmHg.$ Compute the vapor pressures of $A,B,$ and $C,$ and the total vapor pressure above the solution.

$3.(0\mathrm{.}5$ pts$.)$ Boiling Point Elevation & Freezing Point Depression. P $31-36$ Compute the freezing and boiling points of an aqueous solution that is $50\mathrm{.}00\%$ by mass antifreeze. Antifreeze is ethylene glycol: $HO-C{H}_2-C{H}_2-OH.$
