sig. fig. for logs

[Zellmer, Robert]

For the BAR lab you needed to calculate ln[Allura Red].  The sig. fig. for
log(x) and ln(x) are tricky.  It's explained in a help file I have specifically
about logs and s.f. at my "Helpful Tidbit" link.  Sig. fig. for logarithms is
also explained in Appendix A of the textbook.  This is also very important
for ch 16, 17 since you have to take base ten logs to get pH, pOH, etc.
I mentioned this in lecture during our discussion of pH and pOH.  We'll
be dealing with logs again in chapters 19 and 20.  These pesky little
things are popping up everywhere.
