Arsenic molar mass

Allotropes Some elements exist in several different structural forms, called allotropes. Each allotrope has different physical properties. For more information on the Visual Elements image see the Uses and properties section below.

Molar mass of As 4 O 6 is Then, lookup atomic weights for each element in periodic table : As: Weights of atoms and isotopes are from NIST article.

Arsenic molar mass

Arsenic is a chemical element ; it has symbol As and atomic number Arsenic occurs in many minerals, usually in combination with sulfur and metals , but also as a pure elemental crystal. Arsenic is a notoriously toxic metalloid. It has various allotropes , but only the grey form, which has a metallic appearance, is important to industry. The primary use of arsenic is in alloys of lead for example, in car batteries and ammunition. Arsenic is a common n-type dopant in semiconductor electronic devices. It is also a component of the III—V compound semiconductor gallium arsenide. Arsenic and its compounds, especially the trioxide, are used in the production of pesticides , treated wood products, herbicides , and insecticides. These applications are declining with the increasing recognition of the toxicity of arsenic and its compounds. A few species of bacteria are able to use arsenic compounds as respiratory metabolites. Trace quantities of arsenic are an essential dietary element in rats, hamsters, goats, chickens, and presumably other species. A role in human metabolism is not known. Arsenic contamination of groundwater is a problem that affects millions of people across the world. The United States ' Environmental Protection Agency states that all forms of arsenic are a serious risk to human health. The three most common arsenic allotropes are grey, yellow, and black arsenic, with grey being the most common.

Lead components in car batteries are strengthened by the presence of a very small percentage of arsenic, arsenic molar mass. By using this website, you signify your acceptance of Terms and Conditions and Privacy Policy.

Arsenic occurs in many minerals, usually in combination with sulfur and metals, but also as a pure elemental crystal. Inorganic arsenic compounds are found in soils, sediments, and groundwater. These compounds occur either naturally or as a result of mining, ore smelting, and industrial use of arsenic. Organic arsenic compounds are found mainly in fish and shellfish.

Many other countries and districts in Southeast Asia , such as Vietnam and Cambodia , have geological environments that produce groundwater with a high arsenic content. Retrieved 13 May Everything to the right of the line in the periodic table is a non-metal and everything to the left is a metal. Help Text. Sydney veterinarian Percy Sykes stated, "In those days, arsenic was quite a common tonic, usually given in the form of a solution Fowler's Solution In small doses it is toxic and a suspected carcinogen. In chemical formula you may use: Any chemical element. In the s, an arsenic byproduct of dye production, London Purple, was widely used. The vast majority of older pressure-treated wood was treated with CCA. Though the methodology was disputed it did not distinguish between organic and inorganic arsenic the tests showed levels of arsenic up to 36 ppb. These three have been used as agricultural insecticides and poisons.

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. 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

For example, lead hydrogen arsenate was a common insecticide on fruit trees , [74] but contact with the compound sometimes resulted in brain damage among those working the sprayers. This process does not produce any waste stream or sludge and is relatively cheap. X Xenon. Data W. Retrieved 21 September Bulk modulus GPa. Semiconductors: data handbook. When pH is high, arsenic may be released from surface binding sites that lose their positive charge. Add them together: add the results from step 3 to get the total molar mass of the compound. The wallpaper-as-arsenic-source of poison made the headlines in [ These effects have been demonstrated at contaminations less than 50 ppb. WebQC is a web application with a mission to provide best-in-class chemistry tools and information to chemists and students. Some sites may require the addition of an electron acceptor while others require microbe supplementation bioaugmentation. These are found in the periodic table along a diagonal line from Boron at the top left to round about polonium at the bottom right.
