WebFeb 12, 2024 · The second mass loss during the heating step (~0.2%) from 187.5 to 350 °C can be associated with the removal of chemisorbed hydroxyl groups. The third step (~0.4%) occurred between 350 °C and 512 °C, which can be related to the oxidation process of the residual organic materials. No further mass loss was observed up to 512.5 °C until 750 °C. WebExpert Answer. 100% (4 ratings) Molecular formulae of a compound = n * Empirical formulae of t …. View the full answer.
