4. m/11 = 25m/11 × 1 - m × 2. Since each C22 and C8 molecule occupies 12.5 and 5.5 unit cells, respectively, the area occupied by m C22 di-acid molecules can be replaced by 25 m/11 C8 solvent molecules.

6. The strength of the hydrogen-bond formed between two di-acid molecules and between one di-acid molecule and one solvent acid molecule is not available. Here we take the intermolecular hydrogen-bond strength of propionic acid (7.5 ± 0.6 kcal/mol) as a reference.
