<p>In your lab description it tells you to basically:</p>
<p>1. Melt ~12.5 g of paradichlorobenzene (mass it to the 0.01 g).
Try not to go over 70 C</p>
<p>2. As it cools, and when the temp drops below 60 C, start
recording data</p>
<p>3. Repeat 1 and 2 to collect a second set of data<br>
</p>
<p>4. Mass ~1.5 grams of unknown. To the melted
paradichlorobenzene, add and dissolve the unknown</p>
<p>5. As it cools, and when the temp drops below 60 C, start
recording data</p>
<p>6. Re-melt the solution, cool, and take a second set of data with
1.5 g of unknown<br>
</p>
<p>7. Add an additional ~1.5 grams of unknown to the solution after
remelting. Make sure it dissolves</p>
<p>8. As it cools, and when the temp drops below 60 C, start
recording data</p>
<p>9. Re-melt the solution, cool, and take a second set of data with
3.0 g of unknown</p>
<p><br>
</p>
<p>In your lab we are not going to take the second set of data.
Looking at the steps above we will therefore eliminate steps 3, 6,
and 9. This will cut about an hour off of lab. <br>
</p>
<p>I will discuss the best practices for collecting data during the
pre-lab.</p>
<p>Warning -- this is a stinky lab (you are melting mothballs) and
the cleanup is a little more involved. It is getting really nice
outide and lots of people are wearhing shorts. Please come to lab
appropriately clothed. There will not be time to "run back and
change" if you are dressed inappropriately -- and thus take a zero
on this lab.<br>
