The Mole and Avogadro''s Constant - Chemistry LibreTexts
The mass of a mole of substance is called the molar mass of that substance. The molar mass is used to convert grams of a substance to moles and is used often in chemistry. The molar mass of an element is found on the periodic table, and it is the element''s atomic weight in grams/mole (g/mol).

Sodium is the sixth most abundant element in The Earth’s crust, which contains 2,83% of sodium in all its forms. Sodium is, after chloride, the second most abundant element dissolved in seawater. The most important sodium salts found in nature are sodium chloride (halite or rock salt), sodium carbonate (trona or soda), sodium borate (borax), sodium nitrate and sodium sulfate.

Thus sodium chloride (table salt) always contains the same proportion by mass of sodium to chlorine, in this case 39.34% sodium and 60.66% chlorine by mass, and sucrose (table sugar) is always 42.11% carbon, 6.48% hydrogen, and 51.41% oxygen by mass.
Dissolution and precipitation (video) | Khan Academy
- [Voiceover] Let''s say we have some solid sodium chloride, so some salt. And that right there is supposed to be our pile of salt. We''re going to put our salt into some water. We have a beaker containing H2O. The sodium chloride is going to dissolve in the water. So
The Ground State Electron Configuration For Sodium Is
17 · Sodium atoms have 11 protons and so 11 electrons: 2 electrons occupy. edu The ground state electron configuration of an element is the same as the regular configuration in which the electrons are in the lowest possible energy state. $$1s^22s^22p^63s^1

Sodium chloride - Wikipedia
Sodium chloride / ˌ s oʊ d i ə m ˈ k l ɔːr aɪ d /, commonly known as salt (although sea salt also contains other chemical salts), is an ionic compound with the chemical formula NaCl, representing a 1:1 ratio of sodium and chloride ions. NaCl Molar mass 58.443 g/mol
Chem4Kids: Sodium: General Info and Everyday Items
When you purify sodium, you actually wind up with a silvery bright metal that is quite soft and malleable. Sodium is one of the few metals that will float when it is placed in water (H 2 O). Sodium''s atomic mass is less that water''s atomic mass of 18 amu.

Sodium, Chemical Element - reaction, water, uses, …
Compounds of sodium have been known, of course, throughout human history. But sodium metal was not prepared until 1807. The reason is that sodium attaches itself very strongly to other elements. Its compounds are very difficult to break apart. It was
The Elements, sorted by Atomic Mass - Angelo State …
Thus, since the atomic mass of iron is 55.847 amu, one mole of iron atoms would weigh 55.847 grams. The same concept can be extended to ionic compounds and molecules. One formula unit of sodium chloride (NaCl) would weigh 58.44 amu (22.98977 amu
Formula Mass and the Mole Concept · Chemistry
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.”
