A list of all pages that have property "Description" with value "'''Concentration''' [mol·L-1] is a volume-specific quantity for diluted [[sample]]s s. In a concentration, the sample is expressed in a variety of [[format]]s: [[count]], amount, [[charge]], [[mass]], [[energy]]. In solution chemistry, amount concentration is [[amount of substance]] ''n''B per volume ''V'' of the solution, ''c''B = [B] = ''n''B·''V''-1 [mol·dm-3] = [mol·L-1]. The standard concentration, ''c''°, is defined as 1 mol·L-1 = 1 M. [[Count]] concentration ''CX'' = ''NX''·''V''-1 [x·L-1] is the concentration of the number ''NX'' of elementary entities ''X'', for which the less appropriate term 'number concentration' is used by [[Cohen 2008 IUPAC Green Book |IUPAC]]. If the sample is expressed as volume ''V''s (''e.g.'', ''V''O2), then the 'volume-concentration' of ''V''s in ''V'' is termed '[[volume fraction]]', ''Φ''s = ''V''s·''V''-1 (''e.g.'', volume fraction of O2 in dry air, ''Φ''O2) = 0.20946). [[Density]] is the mass concentration in a volume ''V''S of pure sample S. A ''change'' of concentration, d''c''X, in isolated or closed [[system]]s at constant [[volume]] is due to internal transformations ([[advancement per volume]]) only. In closed compressible systems (with a gas phase), the concentration of the gas changes, when pressure-volume work is performed on the system. In open systems, a change of concentration can additionally be due to [[external flow]] across the system boundaries.". Since there have been only a few results, also nearby values are displayed.
