This paper contain results from six previous paper I have published for different galaxies about dark matter density depending on gravitational field. Galaxies studied are NGC 2841, NGC 7331, NGC 3992, M31. All of them are big galaxies bigger than Milky Way. In addition Milky Way was studied with data coming from two authors. Also were studied two intermediate galaxies M33 (Triangulum galaxy) and NGC 3198 Each paper studied dark matter density depending on gravitational field on each galaxy. Rotation curve and dark matter density function depending on radius were taken from paper published by prestigious astrophysics and I got dark matter density depending on gravitational field through a mathematical method. I found that Dark matter density depend on gravitational field according a power function DM density = A•E^B, where A and B are parameters which depend on each galaxy. In this paper are gathered eight different functions belonging to eight different galactic data set and they are tabulated and plotted in order to compare all of them. Conclusion got is that dark matter density depending on gravitational field is very similar on big galaxies whereas DM density is a great deal bigger on intermediate galaxies. The less massive galaxy is the higher DM density is. Results got for big and intermediate galaxies are consistent with author hypothesis which state that dark matter is generated by the own gravitational field. This second version paper include an estimation of total mass in Coma Cluster got through DM density as power of E which is very close to mass calculated by cosmological standard model CDM and NFW profile in a paper published in 2015 by prestigious researchers. This calculus is a test overcome to consider DM density as power of gravitational field as Universal law because that law was got for big galaxies and it has been used to calculated total dark matter inside a galaxy cluster which is 100 times bigger and it contains thousand of galaxies.
