Ba Atomic Number



Molar mass of Ba(NO2)2 = 229.338 g/mol

››More information on molar mass and molecular weight. 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. Distribution in ocean Ba has a nutrient-like vertical profile with moderately depleted concentrations found at the surface and values increasing to a deep maximum. Speciation Barium is present in seawater as the Ba 2+ ion. Residence time The residence time was determined from the global river input of barium and the impacts of estuarine sources of dissolved barium (Chan et al., 1976).

This compound is also known as Barium Nitrite.

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.

Finding molar mass starts with units of grams per mole (g/mol). When calculating molecular weight of a chemical compound, it tells us how many grams are in one mole of that substance. The formula weight is simply the weight in atomic mass units of all the atoms in a given formula.

Formula weights are especially useful in determining the relative weights of reagents and products in a chemical reaction. These relative weights computed from the chemical equation are sometimes called equation weights.

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.

A common request on this site is to convert grams to moles. To complete this calculation, you have to know what substance you are trying to convert. The reason is that the molar mass of the substance affects the conversion. This site explains how to find molar mass.

The atomic weights used on this site come from NIST, the National Institute of Standards and Technology. We use the most common isotopes. This is how to calculate molar mass (average molecular weight), which is based on isotropically weighted averages. This is not the same as molecular mass, which is the mass of a single molecule of well-defined isotopes. For bulk stoichiometric calculations, we are usually determining molar mass, which may also be called standard atomic weight or average atomic mass.

If the formula used in calculating molar mass is the molecular formula, the formula weight computed is the molecular weight. The percentage by weight of any atom or group of atoms in a compound can be computed by dividing the total weight of the atom (or group of atoms) in the formula by the formula weight and multiplying by 100.

About Barium

Barium is a soft light silver metal which belongs to the group of the alkaline earth metals. It is quite reactive and easily reacts with air and water, as well as forms alloys and other chemical compounds. The name of barium comes from a Greek word meaning heavy. It is impossible to find this element in its pure form on our planet, and it is extracted from various minerals and chemical compounds. This element does not exist in the most of biological living organisms, and in its pure form it is quite toxic. Industrial uses of barium include producing various vacuum or cathode tubes, wires, etc. This element found application in producing pigmentation agents and X-ray technology equipment.

Uses of Barium

Barium, a soft, silvery metallic element with the symbol Ba, was mostly used in vacuum tubes, like TV picture tubes. Barium is especially used in alloys with aluminium, nickel, steel, iron, calcium, silicon and manganese. Barium nitrate, an alloy with the formula Ba(NO3)2, can be used in fireworks. Barium sulfate, a compound with the formula BaSO4, is employed in the petroleum industry, as well as in glassmaking, paints, rubbers, plastics, ink, and varnishes. Barium carbonate (BaCO3) is exploited in the manufacture of specialty glass, or in ceramics. The applications of Barium chloride (BaCl2) include laboratories and heat-treating baths.
