Question $2(10$ points$)$

An unknown liquid has a heat of vaporization of $39\mathrm{.}59k\frac{J}{m}$ole. If the normal boiling

point is $84,$ what is vapor pressure $($in torr$)$ of this liquid at room temperature of $25$

degrees C$?$ HINT: Normal boiling point occurs when the vapor pressure of the liquid

is the same as atmospheric pressure $(1$atm or $760mmHg).$

Question $3(10$ points$)$

An unknown liquid has a heat of vaporization of $8\mathrm{.}86k\frac{J}{m}$ole. If the vapor pressure

of this liquid at $-163$ degrees $C$ is $111$ torr, what is the normal boiling point of this

liquid in degrees C$?$ HINT: Normal boiling point occurs when the vapor pressure of

the liquid is the same as atmospheric pressure $(1$atm or $760mmHg).$
