You do realize, I trust, that these densities are functions of both
temperature and pressure? You need to be rather more specific about
conditions, especially for liquid hydrogen (which is quite compressible).

Sutton's "Rocket Propulsion Elements" is a good starting point for things
like this. Ditto the "Handbook of Chemistry and Physics", a standard
scientific reference book. For digging further, properties of the
cryogenic fluids in particular have been examined quite extensively by the
refrigeration people; for example, ASHRAE (American Society of Heating,
Refrigerating, and Air-Conditioning Engineers) publishes "Thermophysical
Properties of Refrigerants" which includes data on a lot of things you'd
never think of as practical refrigerants.
