Atomic Mass is so small you can't actually measure it. So, just like carbon dating, you have to use a relative mass.
the relative atomic mass for the element potassium is 39.0983
Each element on the periodic table has two numbers: the atomic number and the relative atomic mass. The atomic number is the number of protons in the nucleus, and the relative atomic mass is the total number of protons and neutrons (so the difference between them is the number of neutrons). The relative atomic mass is always the higher of the two.
Sodium is a meta element. Atomic mass of it is 23.
Silver is a meta element. Atomic mass of it is 108.
The relative atomic mass is 83.798. So where did you get that it is not determined.
The element with a relative atomic mass of 15.5 is phosphorus.

relative Atomic Mass
It is called the Relative Atomic Mass.
The atomic mass scale is sometimes referred to as the relative atomic mass scale because it is a scale that compares the mass of atoms of different elements to the mass of a carbon-12 atom, which is assigned a mass of exactly 12 atomic mass units. By comparing the masses of atoms relative to carbon-12, scientists can determine the relative masses of different elements.
the relative atomic mass for the element potassium is 39.0983
The relative atomic mass of helium is 4.0026.
The relative atomic mass of magnesium is approximately 24.305.
The chemical element with a relative atomic mass of 173 is Ytterbium (Yb).
The atomic mass of xenon is about 131.29 atomic mass units.
The Relative Atomic Mass of Sodium is 23.
Atomic mass is measured in a unit called an "atomic mass unit". This unit is defined as 1/12 of the mass of a carbon-12 atom at ground state.An atomic mass unit is approximately 1.66053886 x 10-27 kg.Atomic mass is measured in atomic mass units (amu) and Daltons.
