I believe the density will vary, depending on what part of space, for example: (a) The space between the planets within our Solar System, (b) The space between star systems within our Milky Way Galaxy, (c) The space between galaxies, and (d) The space outside of our Local Group (that is, outside of a galaxy group). Also, I don't think the numbers are known precisely. From the Wikipedia article on "Outer Space": "...However, even in the deep vacuum of intergalactic space there are still a few hydrogen atoms per cubic meter." And, in one of the footnotes: "...This source estimates a density of 7 × 10−29 g/cm for the Local Group. An Atomic Mass unit is 1.66 × 10−24 g, for roughly 40 atoms per cubic metre." Note that they are talking about estimates - there is probably no precise information available.
