Question

what is atomic mass​

Answer 1

Answer:The atomic mass (ma) is the mass of an atom. Its unit is the unified atomic mass unit (symbol: u, or Da) where 1 unified atomic mass unit is defined as ​1⁄12 of the mass of a single carbon-12 atom, at rest.[1] The protons and neutrons of the nucleus account for nearly all of the total mass of atoms, with the electrons and nuclear binding energy making minor contributions. Thus, the atomic mass measured in u has nearly the same value as the mass number.

Answer 2

Hello !!

A good answer for your question is, atomic mass is the sum of number of protons and the number of neutrons of a atom. We can say also, atomic mass is the mean of isótopos of a atom and also we can weight according to the occurrence of each element.

FOMULA :

$\boxed{AM=\mathsf{\dfrac{\displaystyle\sum(\texttt{occurrencce\:porcentage}\times~\texttt{atomic\:mass})}{100}}}$

I hope I have collaborated and have a great day !
