Determining The Particle Number
The concept of particle number has a main role in theoretical considerations. In situations where the actual particle number of a given thermodynamical system needs to be determined, mainly in chemistry, it is not practically possible to measure it directly by counting the particles. If the material is homogeneous and has a known amount of substance n expressed in moles, the particle number N can be found by the relation
- N = nNA,
where NA is the Avogadro constant.

Famous quotes containing the words determining the, determining, particle and/or number:
“I esteem it the happiness of this country that its settlers, whilst they were exploring their granted and natural rights and determining the power of the magistrate, were united by personal affection. Members of a church before whose searching covenant all rank was abolished, they stood in awe of each other, as religious men.”

“Each particle is a microcosm, and faithfully renders the likeness of the world.”
