Question

Explain the concepts of relative mass of an atom for expressing the atomic mass of elements​

Answer 1

Answer:

Relative atomic mass is determined by the average atomic mass, or the weighted mean of the atomic masses of all the atoms of a particular chemical element found in a particular sample, which is then compared to the atomic mass of carbon-12.

Explanation:

this is the correct answer to your question

Answer 2

Question :-

Explain the concepts of relative mass of an atom for expressing the atomic mass of elements.

Answer :-

Relative atomic mass (symbol: $\sf{A_r}$ ) or atomic weight is a dimensionless physical quantity defined as the ratio of the average mass of atoms of a chemical element in a given sample to the atomic mass constant. The atomic mass constant (symbol: $\sf{m_u}$ ) is defined as being 112 of the mass of a carbon-12 atom.
