In chemistry, describing a solution with a concentration of one-hundredth of a mole per liter (0.01 M).
From centi- (one-hundredth) plus molar (relating to the mole, a unit of substance quantity). This technical term emerged from 19th-century chemistry when standardized concentration units were developed.
Chemists use centimolar solutions constantly in labs—it's a sweet spot concentration that's dilute enough to be safe but concentrated enough to react measurably, making it perfect for teaching chemistry experiments.
