molality:

see concentrationconcentration,
in chemistry, measure of the relative proportions of two or more quantities in a mixture. The concentration of a solute is very important in studying chemical reactions because it determines how often molecules collide in solution and thus indirectly determines

Variation of ([[DELTA].sub.trs][V.sup.0.sub.[phi]][V.sup.0.sub.[phi]]) with molality is depicted in Figure 5.
Figure 7 shows the viscosities of gel-type electrolytes prepared by three different ionic liquids under the same molality of 0.4 M at different temperatures.
The plots of variations of ultrasonic velocities of solutions of citric acid with molality are shown in the Figure 3.
For a water solution, if the total solute concentration is less than 10 000 ppm and the solution temperature is near 4[degrees]C, molarity and molality may be considered equal and 1 ppm equals 1 mg/L.
This ranged from 30 min to several hours depending on psychrometer model, molality, and measurement conditions (e.g., waiting for full thermal stability after a large temperature change).
Ion activity is a function of activity coefficient and molality. The activity coefficient is determined by ionic strength, ion size, and temperature.
Where: [V.sub.B] is the volume of NaOH solution spent in the blank, [V.sub.G] is the volume of NaOH solution spent in the titration, N is the molality of NaOH, PA is the sample weight and H is the moisture content on the chitosan sample.
"m" represents molality and the superscripts T and B represent top phase and bottom phase, respectively.
where [M.sub.w], [H.sub.2]O is the molecular weight of water, [v.sub.i] is the number of ions in the sail, and [M.sub.i] the molality of the solution.
Like other direct-reading electrochemical biosensors (1), creatinine sensors respond to the molality of creatinine in the sample (amount of creatinine per unit mass of water).
