know the report for exp 14 isn't due until next week.
However,<br>
I've received questions about the pre-lab and some of you
may<br>
start the report and post-lab data entry before then.<br>
<br>
I always get questions from students about getting
negative<br>
values for Ps from eqn 6 in the manual. This is mentioned
in my<br>
help file for exp 14 on the class web page and I've also
discussed<br>
you can't have negative pressures in lecture.<br>
<br>
Here it is again:<br>

KELVIN, KELVIN</b></font><big><font size="2"><big><br>
<br>
Also, you don't need eqn. 6 for the V.P. at the boiling
point taken in<br>
lab or the normal b.p. which you get from the CRC.<br>
<br>
Remember, I have a help file for this exp and an example
for<br>
using Excel and the graph for the 3 compounds studied.
There<br>
should be one graph with the data for the 3 compounds on
the<br>
same graph.<br>
<br>
There use to be an unknown for this experiment. That part
has been<br>
removed. If you see any references to an unknown or a 2nd
graph<br>
in the manual or my web pages for an unknown ignore them.
However,<br>
please let me know so I can make corrections to my files
and the manual.<br>
