There's a couple of mistakes/misprints in the manual for exp 16
(dTf).<br>
<br>
Page 100:<br>
<br>
The eqn at the bottom of the page should have negative sign in it,<br>
<br>
del(T) = <font color="#ff0000"><b>- </b></font>K<sub>f</sub> *
m<br>
<br>
This is the latest iteration of this eqn in the textbook. I'll
explain<br>
this in lecture.<br>
<br>
Page 102:<br>
<br>
The example shows 20.00 mL of cyclohexane (solvent). We've cut<br>
this to 10.00 mL of cyclohexane. So the eqn would be:<br>
<br>
10.00 mL x (0.779 g/mL) x (1 kg/1000 g) = 0.00779 kg cyclohexane<br>
<br>
You're using a buret so the volume may not be exactly 10.00 mL.<br>
<br>
Also, while not an error, for this experiment you're TA will have
you record<br>
your unknown number in your notebook. The Excel file used for the
report<br>
sheet has been modified to include this.<br>
