Atomic Mass Of Magnesium

Magnesium is an important element for plant and animal life. Chlorophylls are porphyrins based upon magnesium. The adult human daily requirement of magnesium is about 0.3 g day-1. Magnesium tarnishes slightly in air, and finely divided magnesium readily ignites upon heating in air and burns with a dazzling white flame.

Computing molar mass (molar weight)

To calculate molar mass of a chemical compound enter its formula and click 'Compute'. In chemical formula you may use:

Any chemical element. Capitalize the first letter in chemical symbol and use lower case for the remaining letters: Ca, Fe, Mg, Mn, S, O, H, C, N, Na, K, Cl, Al.
Functional groups: D, Ph, Me, Et, Bu, AcAc, For, Ts, Tos, Bz, TMS, tBu, Bzl, Bn, Dmg
parantesis () or brackets [].
Common compound names.

Examples of molar mass computations: NaCl, Ca(OH)2, K4[Fe(CN)6], CuSO4*5H2O, water, nitric acid, potassium permanganate, ethanol, fructose.
Molar mass calculator also displays common compound name, Hill formula, elemental composition, mass percent composition, atomic percent compositions and allows to convert from weight to number of moles and vice versa.

Computing molecular weight (molecular mass)

To calculate molecular weight of a chemical compound enter it's formula, specify its isotope mass number after each element in square brackets.
Examples of molecular weight computations: C[14]O[16]2, S[34]O[16]2.

Definitions of molecular mass, molecular weight, molar mass and molar weight

Molecular mass (molecular weight) is the mass of one molecule of a substance and is expressed in the unified atomic mass units (u). (1 u is equal to 1/12 the mass of one atom of carbon-12)
Molar mass (molar weight) is the mass of one mole of a substance and is expressed in g/mol.

Weights of atoms and isotopes are from NIST article.

About Magnesium

Magnesium is a soft metal of light grey color, which can easily burn with bright fire. Magnesium is an essential element for all living things on our planet since a molecule of magnesium is in every cell of chlorophyll, which is the material for photosynthesis. In human body, magnesium is a compound of various enzymes necessary for correct and smooth chemical reactions in our body tissues. Since magnesium is very highly reactive, it can’t be found freely in nature, but it can be obtained from a number of natural sources, manly such minerals as dolomites, magnesites, etc. It is the 8th most abundant element on our planet. It has a variety of uses, primarily as a light but relatively strong metal, especially valuable for producing various consumers’ goods like suitcases, chairs, laptops, etc. Magnesium and its compounds are used to produce fireworks, as well as in medicine (especially for producing spasms reducing medicines, as laxatives, etc.).

Uses of Magnesium

Magnesium (Mg) is the most commonly used structural metal after iron and aluminum. It is especially used in the production of steel and iron to remove sulfur as well as one of the most important construction metals in aircraft and automotive industry. Magnesium is widely used in making mobile phones, cameras, televisions, tablet computers, and laptops.

Its compounds are mostly used in construction, electronics, medicine, and sports. For example, Magnesium chloride, the chemical compound with the formula MgCl2 is used for dust control and ice control. This compound is also used in nutraceutical and pharmaceutical preparations too. It is preferred in the preparation of tofu from soy milk as a coagulant. Magnesium sulfite is used in the producing of paper. Besides, magnesium alloys are very important in the airplane and car construction.

There are some other usages of magnesium as a reducing agent and an additive agent in various industries.

Magnesium is also very important for our body. It helps to convert food into energy, repair DNA and RNA, plays an important role in brain functions, and helps to prevent migraine headaches.
