2.1.1.1 Concentration Measurement The gels were prepared to nominal sodium concentrations using mass measurements, allowing the precise evaluation of the mass of sodium present in each vial, in grams. However, as the samples were prepared by dilution of different quantities of the 5 M NaCl stock solution with the monomer solution of unknown density, without performing volumetric measurements, the actual sodium concentration (molarity) of samples was unknown.
