what is this question? i think U need to rephrase the question.. it's not really understandable.. what to do mean?
Atomic mass is the average mass of all isotopes of a given element.
To get the decimal in an atomic mass, you divide the atomic mass number by 100. For example, if the atomic mass is 23, dividing by 100 would give you 0.23.
Atomic mass - Atomic weight are the same , so look at your periodic table and below every element it will give you atomic mass.
Atomic mass is the total mass of an atom, which includes the mass of protons, neutrons, and electrons. Average atomic mass, on the other hand, is the weighted average of the masses of the isotopes of an element, taking into account the abundance of each isotope in a sample of the element.
Atomic mass represents the total mass of an atom, combining the mass of protons, neutrons, and electrons. Atomic number, on the other hand, is the number of protons in the nucleus of an atom, which determines its chemical properties and element identity.
why would I know this sit would not give me the answer :[
The mass number (similar to the Atomic Mass and not to be confused with atomic number) When the number of protons and neutrons is added the result will be its atomic mass or mass number.
Originally these relative masses were based on hydrogen, known to be the lightest element, having a mass of 1 u, and all the MORE
We make atomic number by number of protons in a atom. We make mass number by total of both protons and neutrons.
Mass number/Atomic Mass

atomic mass - 14 atomic number - 7 It has that because it has 7 protons (and electrons) = the atomic number. And it also has about 7 neutrons and roughly, the mass number = the number of neutrons+ the number of protons.
