The second phase of this study involved a detailed examination of the dataset to gain a comprehensive understanding of its content and to identify any potential limitations that could affect the modeling process. The distribution of decimal logarithmic solubility values in the subCO 2 and scCO 2 datasets is shown in Figure . Given that this distribution approximates a normal distribution, it is anticipated that there will be no systematic bias in the model predictions. The solubility values in the total dataset range from -9.1 to -0.19 on a decimal logarithmic scale, with a mean value of -3.96.
