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.
Direct reading glucose electrodes detect the molality
of glucose in plasma and whole blood.
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).
