The Clausius-Clapeyron Equation (hopefully introduced to you in General Chemistry) can be used to relate the temperature and vapor pressure of a pure liquid given its heat of vaporization. It can be used to create a specialized nomograph for each compound as shown in Figure 6.1 of your text for hydrocarbons and carboxylic acids. In a simplified form it is given in Equation 6.1 of your book for nitrobenzene AH Given that +00-273.15 K Habenzaldehyde)-45.9kmol benzaldshydo boils at 180 "C at 1 atm (760 mm Hg or tor) and that the ideal gas constant is 8.314 4621 Kol if benzaldehyde in your vacuum distillation boiled at 110°C, how good was your vacuum in mm Hg? Provide 2 significant digits in your answers, for instance, 559 should be rounded to 560
