exp 16 (dTf) - Corrections

[Robert Zellmer]

There's a couple of mistakes/misprints in the manual for exp 16 (dTf).

Page 100:

The eqn at the bottom of the page should have negative sign in it,

     del(T) = *- *K_f * m

This is the latest iteration of this eqn in the textbook.  I'll explain
this in lecture.

Page 102:

The example shows 20.00 mL of cyclohexane (solvent).  We've cut
this to 10.00 mL of cyclohexane.  So the eqn would be:

     10.00 mL x (0.779 g/mL) x (1 kg/1000 g) = 0.00779 kg cyclohexane

You're using a buret so the volume may not be exactly 10.00 mL.

Also, while not an error, for this experiment you're TA will have you record
your unknown number in your notebook.  The Excel file used for the report
sheet has been modified to include this.
