Vedclass · Answer

(B) Sodium chloride $(NaCl)$ is an ionic compound that exists as a continuous crystal lattice,not as discrete molecules. Therefore,the term 'molecular mass' is not applicable to it. Instead,we use the term 'formula mass'. The formula mass of $NaCl$ is calculated as the sum of the atomic masses of $Na$ $(23 \ amu)$ and $Cl$ $(35.5 \ amu)$. Formula mass $= 23 + 35.5 = 58.5 \ amu$.
