Ethane molecular mass

At standard temperature and pressure , ethane is a colorless, odorless gas. Like many hydrocarbons , ethane is isolated on an industrial scale from natural gas and as a petrochemical by-product of petroleum refining. Its chief use is as feedstock for ethylene production. Related compounds may be formed by replacing a hydrogen atom with another functional group ; the ethane moiety is called an ethyl group. For example, an ethyl group linked to a hydroxyl group yields ethanol , the alcohol in beverages. Ethane was first synthesised in by Michael Faraday , applying electrolysis of a potassium acetate solution. He mistook the hydrocarbon product of this reaction for methane and did not investigate it further. During the period —, in an effort to vindicate the radical theory of organic chemistry , Hermann Kolbe and Edward Frankland produced ethane by the reductions of propionitrile ethyl cyanide [6] and ethyl iodide [7] with potassium metal, and, as did Faraday, by the electrolysis of aqueous acetates. They mistook the product of these reactions for the methyl radical CH 3 , of which ethane C 2 H 6 is a dimer. This error was corrected in by Carl Schorlemmer , who showed that the product of all these reactions was in fact ethane. At standard temperature and pressure, ethane is a colorless, odorless gas. Solid ethane exists in several modifications. In this form, the positions of the hydrogen atoms are not fixed; the molecules may rotate freely around the long axis. Cooling this ethane below ca. Rotating a molecular substructure about a twistable bond usually requires energy.

The molecular weight of a substance, also called the molar mass , M, is the mass of 1 mole of that substance, given in M gram. Molecular weight is represented by the same number in all unit systems regardless of the system used. For this reason, in many cases the unit for the molecular weight is not mentioned; however, one must realize that it is not a dimensionless parameter. The molecular weight of a pure compound is determined from its chemical formula and the atomic weights of its elements. Example: The molecular weight of ethanol C 2 H 5 OH To calculate the molecular weight of ethanol, the molecular weight of each atom in the molecule is summed:. See also Physical data for hydrocarbons , Physical data for alcohols and carboxylic acids , Physical data for organic nitrogen compounds and Physical data for organic sulfur compounds. Add standard and customized parametric components - like flange beams, lumbers, piping, stairs and more - to your Sketchup model with the Engineering ToolBox - SketchUp Extension - enabled for use with older versions of the amazing SketchUp Make and the newer "up to date" SketchUp Pro.

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. 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.
