This isn't much - really it is part of another post I am working on. The point of this post is to calculate the density of this piece of wood. Really, there is a reason for this. I saw this little ...

Suppose I am working on a problem and I wish to calculate the density of something. I measure the mass to be m = 24.5 grams and the volume is V = 10 cm 3. In this case the density would be: ALERT!

AbstractThe calculation of the molecular column density from molecular spectral (rotational or ro-vibrational) transition measurements is one of the most basic quantities derived from molecular ...
