Isopropyl alcohol, $\mathrm{CH}_{3} \mathrm{CHOHCH}_{3}$, is used in rubbing alcohol mixtures. Alcohol on the skin cools by evaporation. How much heat is absorbed by the alcohol if $2.25 \mathrm{~g}$ evaporates? The heat of vaporization of isopropyl alcohol is $42.1$ $\mathrm{kJ} / \mathrm{mol} .$
Calculate the heat, in kJ, required to evaporate 215 grams of isopropyl alcohol, (CH3)2CHOH. ΔH°vap (molar heat of vaporization at boiling point) = 39.9 kJ/mol MM (molar mass) = 60.11 g/mol

Isopropyl alcohol, $\mathrm{C}_{3} \mathrm{H}_{8} \mathrm{O},$ is marketed as "rubbing alcohol." Its vapor pressure is 100 . torr at $39.5^{\circ} \mathrm{C}$ and 400 . torr at $67.8^{\circ} \mathrm{C}$. Estimate the molar heat of vaporization of isopropyl alcohol.
