Molecular Weight Description

The CYCLOHEXANE molecule consists of 12 Hydrogen atom(s) and 6 Carbon atom(s) - a total of 18 atom(s). The molecular weight of CYCLOHEXANE is determined by the sum of the atomic weights of each constituent element multiplied by the number of atoms, which is calculated to be:

$$ 84.15948 · \frac{g}{mol} $$

The exact term of the above molecular weight is “molar mass”, which is based on the atomic mass of each element. Molecular weight is actually an older term of “relative molar mass” or “molecular mass”, which is a dimensionless quantity equal to the molar mass divided by the molar mass constant defined by 1 g/mol.

Molecular masses are calculated from the standard atomic weights of each nuclide, while molar masses are calculated from the atomic mass of each element. The atomic mass takes into account the isotopic distribution of the element in a given sample.

Additional Information for Identifying CYCLOHEXANE Molecule


  • InChI (IUPAC International Chemical Identifier) information of CYCLOHEXANE

    In addition to the molecular weight information, the structural information of CYCLOHEXANE in a textual expression is available via InChi. The full standard InChI of CYCLOHEXANE is given below:

    InChI=1S/C6H12/c1-2-4-6-5-3-1/h1-6H2

    It can provide a way to encode the molecular information of CYCLOHEXANE to facilitate the search for the compound information in databases and on the web.

    The condensed, 27 character standard InChIKey (hashed version of the full standard InChI) of CYCLOHEXANE is:

    InChIKey=XDTMQSROBMDMFD-UHFFFAOYSA-N

    It may allow easier web searches for CYCLOHEXANE. The InChIKey, however, needs to be linked to the full InChI as well in order to get back to the original structure of the CYCLOHEXANE as the full standard InChI cannot be reconstructed from the InChIKey.
