konsentraatioon

Konsentraatioon is not a standard term in major languages and is usually treated as a misspelling or variant form of concentration. The core idea behind concentration, in any language, is the degree to which a substance, quantity, or attribute is gathered or focused within a defined system.

In science, concentration commonly refers to the amount of a solute in a solution. It is expressed in several ways, such as molarity (moles of solute per liter of solution), molality (moles of solute per kilogram of solvent), mass percent, or parts per million. In materials and environmental contexts, concentration describes how much of a substance is present in a sample or environment, for example impurity concentration or pollutant concentration.

Geography and demography use concentration to describe how densely a feature or population is clustered in a location, such as urban concentration or the distribution of a species. In psychology and education, concentration denotes the ability to maintain focused attention over time, often assessed through tasks that measure sustained attention and resistance to distraction.

Measurement and interpretation depend on the field. Units and metrics vary: chemical concentrations use molarity, percent, or ppm; demographic concentration uses density (people per area); cognitive concentration uses performance measures and reaction times. Etymologically, the proper spellings include concentration in English and konsentraatio in Finnish, among others. See also concentration, density, and attention.
