This is a reminder there is post-lab data entry for exp 14 that must<br>
be completed by the report due date this coming week.<br>
Remember, enter the data for your <font color="#ff0000"><b>UNKNOWN
</b></font>compound.<br>
Also, remember the b.p. for the known compounds you are supposed<br>
to find in the CRC are the normal b.p. (VP of 760.0 mmHg).<br>
For the unknown you measured the b.p. on that particular day<br>
in lab at the prevailing atmospheric pressure in the lab which you<br>
read from the barometer (not likely to be 760.0 mmHg). Make sure<br>
you read the stuff I've sent and on my web page about s.f. for<br>
Ps from eqn 6 and how that translates to s.f. in the ln(Ps). If you<br>
didn't save my e-mails you can find them on my class web page.<br>
<br>
This program is different than the one you used for exp 5 (you used<br>
this newer one for the exp 14 pre-lab). You can find the link on
Carmen,<br>
my web page and the syllabus.<br>
<br>
Please use Firefox. It is the most robust one in terms of how it<br>
works with these programs. I'm sure it has it's own quirks but<br>
the programs were tested pretty thoroughly using Firefox. I know<br>
certain errors are caught when using Firefox which aren't caught<br>
in other browsers. For instance, accidentally leaving a numeric<br>
field blank will be caught by Firefox and it will give you the<br>
opportunity to go back an fix it. Chrome on the other hand will<br>
treat a blank numeric field as a zero and blindly continue on.<br>
Of course this will be a problem for you.<br>
<br>
Our computers are scheduled to be down tomorrow, Friday,<br>
5 PM - 12 AM for maintenance. You may not be able to reach<br>
the servers during this time to enter your data.<br>
<br>
I hope everyone has had a good Spring break so far. I tried to<br>
keep the e-mails to a minimum. I will be sending some out here<br>
shortly about exp 16 which we will be doing next week.<br>
