In the BAR report you need to calculate ln[Allura Red]. The sig.
fig. for <br>
log(x) and ln(x) are tricky. I addressed this in lecture. It's
explained in<br>
a help file I have specifically about logs and s.f. at my "Helpful
Tidbit" link.<br>
Sig. fig. for logarithms is also explained in Appendix A of the
textbook.<br>
This is also very important for ch 16 and 17 since you have to take
base<br>
ten logs to get pH, pOH, etc.<br>
