Other forms: concentrations
In chemistry, concentration is how much of a substance is dissolved in a given amount of liquid. A high concentration, measure the concentration, dilute the concentration.
It is expressed in units such as moles per litre, and diluting a solution lowers it. The everyday sense is the ability to keep your attention on one thing: lose concentration, requires concentration, a lapse in concentration. And a concentration of something means a lot of it in one place: a concentration of shops, a concentration of wealth. Note concentrate, both the verb and the noun for a reduced liquid.

concentration is a gathering to a point.
The word is built from Latin con-, together, plus centrum, a centre — bringing to a common centre. Concentrating the mind and concentrating a solution are the same act of gathering to a point.
