If I understand what you mean by charge density difference, you need to split it up in three different calculations: 1) Full system, e.g. surface + molecule 2) only surface 3) only molecule. It is important that you use the same unit cell and grid sampling for each calculation, even the small molecule.

This difference is significant because it allows specific gravity to provide a direct comparison between substances without needing to reference the units of measurement. For instance, if the density of a substance is 800 kg/m³, and the density of water at 4°C is 1000 kg/m³, the specific gravity of that substance would be: SG=800 /1000=0.8
