WebElectron density or electronic density is the measure of the probability of an electron being present at an infinitesimal element of space surrounding any given point. It is a scalar quantity depending upon three spatial variables and is typically denoted as either () or ().The density is determined, through definition, by the normalised -electron wavefunction … WebI need a high density water solution around 2,5 g/ml. I make and research and saw that the highest one is around 4,2g/ml. I make some experiments and reach 1,9gr/ml with inorganic salts but i need at least 2,5g/ml. key challenge is price when i looked up for more soluble salts they are very expensive like.
