I'll give a right answer but could you please explain more about the question? I'm kind of confuse about which person. like who are they and what opinion did they say or sum?

xxFransisco did not add a picture it was an accident.

Explanation:

i don’t no. suiopgohjk

the relative atomic mass of an element is the mass of one atom of that element, relative to 1/12th of the mass of a  1212c atom. to convert to an absolute mass in kg, it is necessary to multiply by  1.661×10−271.661×10−27.

the relative atomic mass is roughly equal to the number of neutrons, plus the number of protons, in the nucleus of the atom.

for elements with more than one stable isotope (different types of nucleus with different numbers of neutrons but the same number of protons), the quoted mass is usually the average mass, weighted by the relative abundance of the different isotopes.
