<p><font face="serif">Class -- also make sure that you watch the sig
figs on your writeup. If you </font>massed out 1.0000 grams
on the analytical balance then you have 5 sig figs. <br>
</p>
<p>If you know the molar mass of KHP to five sig figs then you can
determine the moles of KHP to 5 sig figs.</p>
<p>BUT when you determine the molarity of NaOH you have less sig
figs in the volume of NaOH, so that affects the sig figs in your
final molarity.</p>
<p>Also pay careful attention to the sig figs in your ALUM lab!<br>
</p>
<p>Like I mentioned before -- I took a quick peek at some of the
work already submitted and found some pretty big errors. Please
check all these things carefully. Both lab reports are due by 11
pm tonight.<br>
