The relative atomic mass of an oxygen atom is $16$. Explain its meaning.
(N/A) The relative atomic mass of an atom is defined as the average mass of the atom as compared to $1/12$th the mass of one carbon-$12$ atom.
Therefore,saying the relative atomic mass of oxygen is $16$ means that one atom of oxygen is $16$ times heavier than $1/12$th of the mass of a carbon-$12$ atom.
