molarity1931
1931 J. C. Ware Analyt. Chem. i. i. 3 Where the solubility is very small, the molarity and the molality of the solution will be approximately the same.
1951 M. A. Paul Princ. Chem. Thermodynamics vii. 388 The molarity of a given solution evidently varies in general with temperature.
1973 H. Block & A. K. Holliday Mod. Physical Chem. ix. 203 In general, molarities cannot easily be related either to mole fraction or to molality, unless the changes in volume on dissolution are either negligible or can be allowed for.
1993 Dyes & Pigments 21 3 The addition rates of both reactants were adjusted in such a way that they were introduced evenly (in terms of molarity) and slowly.
