It would be misleading to talk about molecular mass of a salt because salts (ionic compounds) are not molecules. The concept of âformula massâ is a formalism that recognizes that salts are not molecules. The formula mass is calculated from the simplest formula of an ionic compound just like the molar mass is calculated from the molecular formula of a covalent compound: by adding up the atomic masses of all the atoms in the formula.
Atomic mass - Conversion factor between atomic mass units and grams. 1  The standard scientific unit used to quantify the amount of a substance in macroscopic quantities is the mole (symbol: mol), which is defined arbitrarily as the amount of a substance which has as many atoms or molecules as there are atoms in 12 grams of the carbon isotope C-12.
