molaarisesti

Molaarisesti is a Finnish adverb derived from the adjective molaarinen, meaning molar in the sense of relating to the mole or to molarity. It is used primarily in scientific Finnish to describe actions, quantities, or measurements that are defined in terms of amount of substance (moles) or in terms of molar concentration (moles per liter). In practice, the term signals that a procedure or description is expressed with mole-based quantities rather than mass- or volume-based measures.

Etymology and form: The word combines molaarinen with the adverbial suffix -isesti to form molaarisesti. The root mol- reflects the concept of a mole, the SI unit for amount of substance, and is closely linked to the concepts of molarity (pitoisuus mol/L) and related measures. The corresponding nouns include molaarisuus (molarity) and, in some contexts, molaarinen pitoisuus.

Usage and context: Molaarisesti is most common in formal or technical writing, such as chemistry textbooks, research articles, and laboratory protocols. It is used to qualify statements about quantities or procedures that are defined by mole-based values. In everyday Finnish, speakers more often use nouns like "molaarinen pitoisuus" rather than the adverb, but molaarisesti appears when an adverbial description is needed, for example to describe how a step should be performed according to mole ratios or molar concentrations.
