En este trabajo, se prepararon cinco solventes pseudobinarios (agua + [Na.sub.2]S[O.sub.4]), con una concentracion en la escala molal respecto a la sal dada entre parentesis: I (0.2002 m), II (0.5998 m), III (0.9005 m), IV (1.2000 m) y V (1.6001 m), para ser mezclado con cantidades apropiadas de DL-Alanina.

The formal concentrations of Cu and Cl are 1 molal, but since there were only one Cu and one Cl in the simulation box, there were no Cl-Cl or Cu-Cu interactions, which is consistent with the high dilution in vapors.
The total volume for lot 1 is approximately 1,820,000 molal per year.
The probability of forming even a single knot in organic polymers of similar molecular weight is <1, a consequence of both lower flexibility on a molecular level and higher free molal volume.
Shoumkova y Stoyanova (2013), usaron cenizas de carbon con un contenido en peso de 42% de SiO2 y 20% de Al2O3, para activacion hidrotermica con soluciones de NaOH y KOH, 1,6, 3,1, 6,2 y 12,5 molal, y usando proporciones de 10 g de cenizas por cada 100 mL de alcali.
