So during the laboratory experiment the following targets have been attained:
0) grasp of problematic nature that is still staying at
experience's heart.
1) calculation of Avogadro constant with a significant
figure of precision.
2) construction of a method able to exceed material and
and intellectual intricacies in the recognition of some matter's deep structure sparks.
3) grasp of historical situation and way in which are
enclosed scientific contribution that permitted such outgrowing.
We haven't absolutely attained the aim to restrict data requisite for the
experiment to the only measurements done in lab, but we needed to refer to
concepts maybe difficults to understand (Approximation error theory, properties
of oleic acid, bond lengths...)
On the other hand, theese ones are available for the most part first of all
on the Net (Wikipedia excels),
as well as in tables of physical chemistry (we particularly advise Küster-Thiel, Tabelle
per le analisi chimiche e chimico-fisiche, HOEPLI) but also in high school
textbook (in Valiutti-Tifi-Gentile, Le idee della chimica,
Zanichelli you can even find a concise life of Avogadro), and you don't have to
be a specialist to get it summarily.

The "Accademia
dei quaranta" wrote brief pages about European and Italian chemistry's
history (from which come, many bits of information we gave about Avogadro).
We recommend about last evaluation of Avogadro number the reliable and
already quoted CODATA (and http://physics.nist.gov/cuu/Constants/index.html),
or even more the 1972 edition of The International System of Units (SI),
National Bureau of Standards Special Publication.
For useful physical & mathematical notions not only purely scholastic, I
suggest finally my teacher's site:
