This is the missing-mass problem. If this factor of ten holds throughout the Universe, then the total mass in the Universe would be about 6e52 kg. If the missing mass were mostly in the form of hydrogen atoms (which is not at all clear) then the number of atoms would be about 4e79.
The visible universe is estimated to contain between 1078 and 1080 atoms. This is the estimated number of atoms in the observable universe, but since we do not know the absolute size of the universe, we cannot be certain. Most of the matter in the universe is still hydrogen.
