However it may have mutagenic effect. molar mass and molecular weight, Convert grams Sodium Thiosulfate to moles. In addition, these suggestions should not be confused with nor followed in violation of applicable laws, regulations, rules or insurance requirements applicable. Flammability of the Product: May pose a fire hazard when exposed to elevated temperatures or by contact with an ignition source. Dispose of container and unused contents in accordance with federal, state and local requirements. You can sign in to vote the answer. can you give me the equation to explain please. P303+P361+P353 - IF ON SKIN (or hair): Remove/Take off immediately all contaminated clothing. Sodium thiosulfate has the chemical name thiosulfuric acid, disodium salt, pentahydrate. Boiling Point: Not available name for ch3-c(ch3)(oh)-ch3. : 10102-17-7 for pentahydrate Create. FIRST-AID MEASURES Eyes Rinse with plenty of water for at least 15 minutes and seek medical attention if necessary. Classification according to Regulation (EC) No 1272/2008. Get medical attention. This material does not contain any hazardous air pollutants. We use the most common isotopes. Sodium Thiosulfate; Sodium Thiosulfate. Sodium Thiosulfate BP USP IP ACS Analytical Reagent FCC Food Grade Manufacturers, Sodium Thiosulfate Pentahydrate SDS GHS, MSDS Sheet, Material Safety Data Sheet. Molecular Weight: 248.18 The reason is that the molar mass of the substance affects the conversion. TSCA Significant New Use Rule: None of the chemicals in this material have a SNUR under TSCA. Flash Points: NA. Bioaccumulative potential Sodium Thiosulfate, Pentahydrate (10102 -17 -7) Log Pow -4.35 Bioaccumulative potential Not established. OSHA Hazards: No hazard as per OSHA. Section 313: No chemicals are reportable under Section 313. Wash clothing before reuse. Finish cleaning by spreading water on the contaminated surface and dispose of according to local and regional authority requirements. Flammable Limits: NA. Handle in accordance with good industrial hygiene and safety practice. Use appropriate tools to put the spilled solid in a convenient waste disposal container. If the formula used in calculating molar mass is the molecular formula, the formula weight computed is the molecular weight. Avoid formation of dust and aerosols. This is how to calculate molar mass (average molecular weight), which is based on isotropically weighted averages. HMIS (Perceived): Health hazard: 0, Flammability: 0, Physical hazards: 0 Hazards not otherwise classified (HNOC): This substance is not classified as dangerous according to Directive 67/548/EEC. Dust deposits on floors and other surfaces may pick up moisture and cause the surfaces to become slippery and present safety hazards. I went to a Thanksgiving dinner with over 100 guests. Thoroughly clean shoes before reuse. Clean Air Act: The physical and chemical properties of Na 2 S 2 O 3 are listed below. These relative weights computed from the chemical equation are sometimes called equation weights. Use means suitable for extinguishing surrounding fire. Canada WHMIS Classifications: D2B Solubility: Readily soluble in water Having molecular formula of Na2S2O3.5H2O & molecular weight of 248.18, the chemical is available in form of white crystal/crystalline powder form and has minimum assay of 96.0%. Remove contact lenses, if present and easy to do. This site explains how to find molar mass. Environmental Fate: No information found. Melting Point: 48C Recommended usage: Industrial Manufacturing.

Hazardous Decomposition Products: It emits toxic oxides of carbon and oxides of sulfur hydrogen sulfide along with sodium oxide when heated to decomposition. 5H 2 O. Molecular Weight: 248.18. Hazardous Polymerization: Will not occur. CAS No. Finding molar mass starts with units of grams per mole (g/mol). Properties of Sodium Thiosulfate. None of the chemicals in this product are listed as Hazardous Substances under the CWA. Australian Hazchem Code: None The structural formula is: Structure of Sodium Thiosulfate Pentahydrate. The product itself and its products of degradation are not toxic. This is not the same as molecular mass, which is the mass of a single molecule of well-defined isotopes. So it's weight is (23.0x2 + 32.1x2 + 16.0x3), Electrons normally have no relevance to mass since they have such a small mass (~0.0005). : 10102-17-7 for pentahydrate This pentahydrate of sodium thiosulfate is described by the following chemical formula: Na 2 S 2 O 3.5H 2 O.
