molalityn.

1923 G. N. Lewis & M. Randall Thermodynamics iv. 33 When we speak of a molal or tenth molal aqueous solution.., we shall refer, not to the concentration, but to the number of mols of solute in 1000 grams of water, which we may call the molality.

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.

1963 W. J. Moore Physical Chem. (ed. 4) v. 117 One advantage of molality is that it is easy to prepare a solution of given molality by accurate weighing procedures.

1970 Man. Symbols & Terminol. Physicochem. Quantities & Units (I.U.P.A.C.) 12 A solution having a molality equal to 0·1 mol kg⁻¹ is sometimes called a 0·1 molal solution.

1992 Jrnl. Physical Chem. 96 404/2 The standard potential[s]..were determined at each of the experimental temperatures from measurements of the emf of cell A with a molality of hydrochloric acid equal to 0.01 mol kg⁻¹.
