# 21 Determining Avogadro's Number Using a Monolayer

2 Fatty acid monolayers are easy to form, provided all surfaces are free of any foreign particles. The solvent used is a low-boiling mixture of pentanes (C 5 H 12) and hexanes (C 6 H 14) called "petroleum ether" that evaporates completely and rapidly.

Estimation of Avagadro's Number

The volume of the monolayer can also be calculated using the surface area and approximated size the acid molecules, which can then be used to estimate the number of the acid molecules in the monolayer.


The thickness, area and volume of the monolayer are related by the following equations: Area ( of a circle) = π * (radius) 2 Volume (of a cylinder) = Area * Thickness Thickness = Volume / Area Model of a "monolayer" Area Thickness Diameter = 2 x radius Figure 1. 5.0 nm x 5.0 nm Scanning Tunneling Microscope image ...
