Computing the molar volumes using the method of Parsons and Ninham (2009) yielded volumes of 1,033 cc/mole and 1,069 cc/mole for figures 7G and 7I respectively, corresponding to NaCl concentrations of 0.967M and 0.935M of NaCl. Likewise, H4SiO4 concentrations are double these numbers at 1.934M and 1.870M and are 3 orders of magnitude higher than saturation
