<p><font face="serif">The solution to quiz 2 is posted on the class
website. Many of you missed the problems related to
intermolecular forces. These were very similar to the problem
in Aktiv -- so make sure you are getting those done to help you
prepare for the quiz/test.</font></p>
<p><font face="serif">Also, the value of R you needed was 8.314
J/deg-mol. As I mentioned in class, there are really only two
values of R we use in Gen Chem --</font></p>
<ul>
<li><font face="serif">0.08206 L-atm/deg-mol <br>
</font></li>
<li><font face="serif">8.314 J/deg-mol</font></li>
</ul>
<p><font face="serif">You need to memorize BOTH of these as well as
their units and know when to use them. Finally, many of you
plugged in the enthalpy of vaporization in kJ/mol into the given
equation -- it had to be converted to J/mol so that the units
would cancel properly with R.</font></p>
