What is the standard for comparison for the relative masses listed n the periodic table?
The standard comparison for atomic weights on the Periodic Table is carbon 12. This is a common isotope of carbon which has 6 protons and 6 neutrons. Carbon 12 is assigned an Atomic Mass of 12, and other elements' atomic masses are all relative to this value.

Atomic mass in the periodic table?
Atomic mass, also known as atomic weight, is the average mass of an atom of an element based on the relative abundance of its isotopes. It is listed in the periodic table below the element's symbol. Atomic mass is measured in atomic mass units (amu) and provides information about the element's mass compared to a standard carbon-12 atom.
Why the relative atomic numbers of some elements are not shown in the periodic table?
All known elements are listed on the periodic table of the elements. Historical tables did not have elements listed that were unknown at the time. For instance, Dimitri Mendeleev, who laid out the first successful periodic table in 1869, did not have any of the noble gases listed since none of them had been discovered at that time. Modern periodic tables have gaps at the lower right end where elements are expected to be created in labs in the future, but have not been successfully created yet.
What element has a relative atomic mass of 15.5?

Atomic weight, which is the mean relative mass and is dimensionless.
How is the relative atomic mass calculated for elements on the periodic table?
The relative atomic mass of an element is calculated by taking the weighted average of the masses of its isotopes, based on their abundance in nature. This value is listed on the periodic table below the element's symbol.
