![]() ![]() If the formula used in calculating molar mass is the molecular formula, the formula weight computed is the molecular weight. These relative weights computed from the chemical equation are sometimes called equation weights. For bulk stoichiometric calculations, we are usually determining molar mass, which may also be called standard atomic weight or average atomic mass.įormula weights are especially useful in determining the relative weights of reagents and products in a chemical reaction. This is not the same as molecular mass, which is the mass of a single molecule of well-defined isotopes. This is how to calculate molar mass (average molecular weight), which is based on isotropically weighted averages. The atomic weights used on this site come from NIST, the National Institute of Standards and Technology. Using the chemical formula of the compound and the periodic table of elements, we can add up the atomic weights and calculate molecular weight of the substance. This site explains how to find molar mass. The reason is that the molar mass of the substance affects the conversion. To complete this calculation, you have to know what substance you are trying to convert. The formula weight is simply the weight in atomic mass units of all the atoms in a given formula.Ī common request on this site is to convert grams to moles. When calculating molecular weight of a chemical compound, it tells us how many grams are in one mole of that substance. The name "Magnesium" originates from a Greek district in Thessaly called Magnesia.In chemistry, the formula weight is a quantity computed by multiplying the atomic weight (in atomic mass units) of each element in a chemical formula by the number of atoms of that element present in the formula, then adding all of these products together.įinding molar mass starts with units of grams per mole (g/mol). Commercially, magnesium is primarily used in the creation of strong and lightweight aluminum-magnesium alloys, which have numerous advantages in industrial applications. It is can be found in minerals such as brucite, carnallite, dolomite, magnesite, olivine and talc. In its elemental form, magnesium has a shiny grey metallic appearance and is an extremely reactive. Magnesium is the eighth most abundant element in the earth's crust and the fourth most common element in the earth as a whole. Magnesium was discovered by Joseph Black in 1775 and first isolated by Sir Humphrey Davy in 1808. The magnesium atom has a radius of 160 pm and a Van der Waals radius of 173 pm. The number of electrons in each of Magnesium's shells is and its electron configuration is 3s 2. Magnesium (atomic symbol: Mg, atomic number: 12) is a Block S, Group 2, Period 3 element with an atomic mass of 24.3050. Additional technical, research and safety (MSDS) information is available as is a Reference Calculator for converting relevant units of measurement. Typical and custom packaging is available. American Elements produces to many standard grades when applicable, including Mil Spec (military grade) ACS, Reagent and Technical Grade Food, Agricultural and Pharmaceutical Grade Optical Grade, USP and EP/BP (European Pharmacopoeia/British Pharmacopoeia) and follows applicable ASTM testing standards. Metallic carbide materials are marketed under the trade name AE Carbides. They often have other valuable properties in combination with toughness, such as electrical conductivity, low thermal expansion and abrasiveness. Like diamond, a pure carbon substance, carbide compounds tend to be extremely hard, refractory and resistant to wear, corrosion and heat, making them excellent candidates for coatings for drills and other tools. Carbides are compounds in which the anion is one or more carbon atoms. Magnesium Carbide is available in numerous forms and custom shapes including discs, rods, sputtering targets, or other forms upon request.
