Less<< Dimethyl sulfoxide-D6 MSDS (material safety data sheet) or SDS, CoA and CoQ, dossiers, brochures and other available documents. National Institute of Standards and Technology U.S. Also known as: Dimethyl sulfoxide Methyl sulfoxide Methylsulfinylmethane.Įlements: Carbon (C), Hydrogen (H), Oxygen (O), Sulfur (S).Boiling Point (BP), DMSO changes its state from liquid to gas at 189☌ (372.2☏ or 462.15K).Melting Point (MP), DMSO changes its state from solid to liquid at 18.45☌ (65.21☏ or 291.6K).In Imperial or US customary measurement system, the density is equal to 68.75816 pound per cubic foot, or 0.63665 ounce per cubic inch. density of dMSO is equal to 1 101.4 kg/m³ at 20☌ (68☏ or 293.15K) at standard atmospheric pressure. DMSO weighs 1.1014 gram per cubic centimeter or 1 101.4 kilogram per cubic meter, i.e.CO 2 has one carbon atom and two oxygen atoms.Oxygen (O) has an atomic mass of about 16.00 amu.Carbon (C) has an atomic mass of about 12.01 amu.Let's calculate the molar mass of carbon dioxide (CO 2): Add them together: add the results from step 3 to get the total molar mass of the compound.Calculate molar mass of each element: multiply the atomic mass of each element by the number of atoms of that element in the compound.Handouts can provide only necessary information during test taking. Hide unnecessary or grade-level inappropriate information. The atomic mass is usually found on the periodic table and is given in atomic mass units (amu). Ptables new, up-to-date periodic table PDF and wide periodic table PDF are layered so you can choose exactly what you want to print, and are the perfect companion to the periodic table classroom poster. Sheets of printer paper are packaged in reams of 500, a seemingly large number. (12), and pencils often come in a gross (12 dozen, or 144). Find atomic masses: look up the atomic masses of each element present in the compound. B Obtain the atomic masses of each element from the periodic table and multiply the atomic mass of each element by the number of.For example, water is H 2O, meaning it contains two hydrogen atoms and one oxygen atom. Identify the compound: write down the chemical formula of the compound.One mole contains exactly 6.022 ×10 23 particles (Avogadro's number) Mole is a standard scientific unit for measuring large quantities of very small entities such as atoms and molecules.Molar mass ( molar weight) is the mass of one mole of a substance and is expressed in g/mol.(1 u is equal to 1/12 the mass of one atom of carbon-12) Molecular mass ( molecular weight) is the mass of one molecule of a substance and is expressed in the unified atomic mass units (u).To calculate molecular weight of a chemical compound enter it's formula, specify its isotope mass number after each element in square brackets.Įxamples of molecular weight computations: NIST/TRC Web Thermo Tables (WTT) NIST Standard Reference Subscription Database 3 - Professional Edition Version 2-2012-1-Pro This web application provides access to a collection of critically evaluated thermodynamic property data for pure compounds with a primary focus on organics. Molar mass calculator also displays common compound name, Hill formula, elemental composition, mass percent composition, atomic percent compositions and allows to convert from weight to number of moles and vice versa.Ĭomputing molecular weight (molecular mass) Functional groups: D, Ph, Me, Et, Bu, AcAc, For, Tos, Bz, TMS, tBu, Bzl, Bn, DmgĮxamples of molar mass computations: NaCl, Ca(OH)2, K4, CuSO4*5H2O, nitric acid, potassium permanganate, ethanol, fructose, caffeine, water.Capitalize the first letter in chemical symbol and use lower case for the remaining letters: Ca, Fe, Mg, Mn, S, O, H, C, N, Na, K, Cl, Al.
