The atomic mass of an atom is obtained by taking the sum of the atomic masses of different isotopes of the element.

Vedclass · Answer

(C) Atomic mass is defined as the weighted average of the masses of all naturally occurring isotopes of an element. This is calculated by multiplying the mass of each isotope by its fractional natural abundance and summing these values. Option $(a)$ is true as atomic mass is relative to the ${}^{12}C$ standard. Option $(b)$ is true as the atomic mass of $Na$ is $23 \ u$. Option $(d)$ is true as it describes the definition of average atomic mass. Option $(c)$ is incorrect because it suggests a simple sum of masses rather than a weighted average based on natural abundance.
