<p>Dr. Pounds, I am really confused about the pre-lab quiz. How
can I find the freezing point depression constant for p-DCB
when I have no
<strong>ΔT, </strong>and have no moles of solute or grams
solvent? Am I supposed to use what I recorded in lab for this?
And does the second question rely on the answer from the first
question?</p>

The freezing point of the pure solvent and the freezing point of the
solution are given in the prelab question. <img

would then be the difference between these two. The information
related to the <img style="vertical-align: middle"
src="cid:part2.09070604.02060502@mercer.edu" alt="$K_f$"> value
for is needed to answer both questions. That is found in the lab
manual.<br>
<br>
I will be doing this in class tomorrow.<br>
