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.
Isopropyl alcohol has a heat of vaporization of 3.99 x 10^4 J mol^-1 and a boiling point of 82.30 °C at 1.000 atm. Using the Clausius-Clapeyron equation, calculate the vapor pressure of isopropyl alcohol at 35.00 °C. 0.411 atm None of these 0.998 atm 7.94 atm 0.126 atm

isopropyl alcohol, CH3CHOHCH3, is used in rubbing alcohol mixtures. Alcohol on the skin cools by evaporation. How much heat is absorbed by the alcohol if 3.17 g evaporates? The heat of vaporization of isopropyl alcohol is 42.1 kJ/mol.
