Question

58.5 amu are termed as formula mass not molecular mass of NaCl. why?​

Answer 1

Explanation:

In NaCl, there is no sharing of electrons, rather the transfer of electrons is taking place. As the term molecular mass is used in reference to molecules only and not ions, therefore for NaCl we use the term formula mass. 58.5 amu is the formula mass of nacl but not the moleculer mass.
