Yes they are; they are not the constants that they were once considered to be.
density = mass\volume.
Relative atomic mass, also called atomic weight, is listed on the periodic table for each element. There is no element listed on the periodic table with a relative atomic mass of 15.5.

electron = relative charge = 1- relative mass = 1/1840 proton = relative charge = 1+ relative mass = 1 neutron = relative charge = 0 relative mass = 1
It is a measure which gives the relative mass of an element (or compound) - relative to 12C having a mass of 12.
All elements have an atomic mass relative to 12C having a mass of 12.
Jupiter has the greatest mass relative to Earth.
the relative atomic mass for the element potassium is 39.0983
the relative molecular mass or molecular weight of a compound is the mass of a molecule of the compound relative to the mass of a carbon atom taken as exactly 12.
The relative atomic mass is 131.293
1/1840 the mass if a hydrogen atom.
