15 Fe 1 Table 2: Saturation index, molality
and activity of different mineral phases in Geno hot spring.
Direct reading glucose electrodes detect the molality
of glucose in plasma and whole blood.
2]O following the experimental approach --that is, isomolal solutions with respect to NaCl--, the variation of the transition temperature gypsum-anhydrite with the NaCl molality
(or the water activity) can be obtained.
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.
Fe2+] is the molality
of the ferrous iron in the solution and P[O.
This same sort of repetitive testing can be done with many concepts such as moles, molarity, molality
, the periodic table, quantum numbers, and so forth.
0] is unit molality
, m is molality
of the solution, [phi] is the osmotic coefficient of the solution and [M.
Electromotive-force measurements of cells containing hydrochloric acid and Holmium chloride at constant total molality
have been used to determine the variation of the logarithm of the activity coefficient of hydrochloric acid with change in the amount of Holmium chloride in the solution.
Sodium chloride calibration solutions were used throughout as water potential standards, and the combined effect of temperature and molality
on water potential was taken from the tables by Lang (1967).
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).
