One of these is the sodium/metal chloride, which in addition to beta"-alumina has a secondary electrolyte (NaAlCl 4) to conduct ions from the first electrolyte to the hode. This is necessary because the metal chloride is a solid. v Nickel/Sodium Cells
Electrolytic Cells - Purdue University
Sodium metal that forms at the hode floats up through the molten sodium chloride into a sodium-collecting ring, from which it is periodically drained. The diaphragm that separates the two electrodes is a screen of iron gauze, which prevents the explosive reaction that would occur if the products of the electrolysis reaction came in contact.

Atomic Mass of Chemical Elements - Periodic Table
The atomic mass or relative isotopic mass refers to the mass of a single particle, and therefore is tied to a certain specific isotope of an element. The atomic mass is carried by the atomic nucleus, which occupies only about 10 -12 of the total volume of the atom or less, but it contains all the positive charge and at least 99.95% of the total mass of the atom.
Salt - Wikipedia
Salt is a mineral composed primarily of sodium chloride (NaCl), a chemical compound belonging to the larger class of salts; salt in its natural form as a crystalline mineral is known as rock salt or halite.Salt is present in vast quantities in seawater, where it is the main mineral constituent., where it is the main mineral constituent.

The formula mass for an ionic compound is calculated in the same way as the formula mass for covalent compounds: by summing the average atomic masses of all the atoms in the compound’s formula. Keep in mind, however, that the formula for an ionic compound does not represent the composition of a discrete molecule, so it may not correctly be referred to as the “molecular mass.”
