![]() For bulk stoichiometric calculations, we are usually determining molar mass, which may also be called standard atomic weight or average atomic mass. This is not the same as molecular mass, which is the mass of a single molecule of well-defined isotopes. Other human data: Symptoms have occurred after 30 minutes of exposure to concentrations ranging from 420 to 510 ppm while exposure to 4,800 ppm for 30 minutes causes coma and may be fatal Flury and Zernik 1931. This is how to calculate molar mass (average molecular weight), which is based on isotropically weighted averages. Other animal data: RD 50 (mouse), >81,000 ppm AIHA 1992. The atomic weights used on this site come from NIST, the National Institute of Standards and Technology. 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. 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. 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.įormula weights are especially useful in determining the relative weights of reagents and products in a chemical reaction. This site explains how to find molar mass. The reason is that the molar mass of the substance affects the conversion. Chemical Identifiers What is this information NFPA 704 (NFPA, 2010) General Description A clear colorless to light yellow volatile liquid with a strong disagreeable odor. Eye exposure may cause degeneration of the retina and optic nerve. To complete this calculation, you have to know what substance you are trying to convert. Carbon disulfide is a strong skin irritant dermal exposure may result in severe burns. 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. In contrast, impure carbon disulfide, typically utilized in several manufacturing purposes, is a yellowish. Carbon disulfide is a colorless liquid having a pleasing smell, somewhat similar to chloroform. When calculating molecular weight of a chemical compound, it tells us how many grams are in one mole of that substance. Carbon disulfide, also known as carbon bisulfide or disulfide carbon is a chemical name for CS2, which consists of carbon and sulfide ions. These are just some of the reasons many industrial and clinical labs, as well as technical inspectors give us their samples for parameter analysis.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). biodegradation of CS2 is occurring and stable carbon isotopes are a promising tool to quantify CS2 degradation. The people most often exposed to carbon disulfide are workers in plants that use carbon disulfide in their manufacturing processes. ![]() It is not clear how long carbon disulfide stays in the air. Molecular weight calculation: 12.0107 + 32.0652. Small amounts of carbon disulfide can enter the air by evaporation and as a by-product of several manufacturing processes. We will do everything we can to find the best solution.Ī team composed of scientists will follow every stage of your project. Calculate the molar mass of Carbon Disulfide in grams per mole or search for a chemical formula or substance. ![]() Copy Sheet of paper on top of another sheet.

Carbon disulfide Synonyms & Trade Names Carbon bisulfide CAS No. ![]() Most of our laboratories are certified and/or accredited. Our objective first and foremost is to connect you with laboratories we partner with providing the analysis you need. For this analysis, the lab adopts the following method: Inhouse. Carbon disulfide (CS2) has been historically associated with the production of rayon, cellophane, and carbon tetrachloride. Specimens must be collected using specialist equipment. The parameter : Carbon disulfide (CS2), n☇5-15-0 is measured by HS/GC-MS. ![]()
