Let the mass of each gas present in the mixture be mi. Then the mass balance gives the total mass of the mixture mm as (12.1)mm=m1+m2+⋯+mN=∑i=1Nmi The corresponding number of moles ni of gas i with molecular mass Mi can be determined from Eq. (1.9) as (1.12)ni=mi/Mi ...
The densities of methanol, ethanol, 1-propanol, 1-butanol and 1-hexanol were measured in aqueous solutions of sodium dodecylsulfate at 25掳C. The partial molar volumes of the alcohols at infinite dilution in the aqueous surfactants solutions were calculated and discussed using a mass-action model...
1-decanolThe solubility of 1-butyl-3-methylimidazolium octylsulfate, [BMIM][OcSO 4 ], has been determined in hydrocarbon ( n -hexane, n -heptane, n -octane or n -decane) solutions and alcohol (methanol, 1-butanol, 1-hexanol, 1-octanol or 1-decanol) solutions. Densities and excess ...
χg is the mass susceptibility of the solute, Δυ is the observed shift in the frequency of the reference compound (t-butanol), υ is the frequency of the spectrometer, and m is the mass of the complex per cm3 of solvent. χm=610001cΔυυ χm is the molar susceptibility of the ...

“microdosing” studies to evaluate the pharmacokinetics of novel drug compounds22,23,24,25, extends the distance/time over which tracers can be transported to the imaging site26, and is critical in preclinical research, where much higher concentrations of the tracer per mass of the animal must...
Mole fractions of these samples were determined by measuring the mass of each component with a precision balance Sartorius, model CP 225D, ±0.01 mg. Table 1.Experimental speed of sound and density of pure liquids with literature values at T= (298.15, 303.15, 308.15, 313.15, and ...
The observed trends of this quantity as a function of the surfactant concentration were rationalized using a mass-action model for the alcohol distribution between the aqueous and the micellar phase. At the same time, the model was revised to account for the alcohol effect on the surfactant ...
Densities of the ternary system water-sodium dodecylsulfate (NaDS)-pentanol and of the binary systems butanol-octane and pentanol-octane were measured at 15, 25, and 35 掳C. The apparent molar volume of pentanol in the ternary system was analyzed using a mass-action model for the alcohol ...
