The molecular formula specifies the number of atoms of each element in one molecule. For iso-octane this is C8H18. This means that there are 8 atoms of carbon and 18 atoms of hydrogen in one molecule of C8H18. This also means that in one mole of iso-octane, there are 8 moles of carbon and 18 moles of hydrogen.
As shown in Table 2, the average iodine adsorption number per gram of the carbon black of the set of E2-1ËE2-5 is 124.8 mg as compared to 126 mg per gram of the carbon black sample determined by the titration method according to the standard of ASTM-D1510.
