<p>The enthalpy of vaporization of acetone is 32.0kJ/mol. Thenormal boiling point of acetone is 56.5 degrees Celcius. What isthe vapor pressure of acetone at 25 degreesCelcius?</p>
<p>Ok I think I need to use the Clausius-Clapeyronequation: </p>
<pre> <em>P</em><sub>1</sub> <spanstyle="font-family:symbol;">D</span><em>H</em><sub>vap</sub>1 1
ln (---) = ---- (--- - ---)
<em>P</em><sub>2</sub><em>R</em><em>T</em><sub>2</sub><em>T</em><sub>1</sub></pre>
<p>but then I only have 4 out of the 6 unknowns, delta H, T2,T1 and R. If this is the correct method, then how do I findP1?</p>
