Molecular Weight Description

The TEPP molecule consists of 20 Hydrogen atom(s), 8 Carbon atom(s), 7 Oxygen atom(s), and 2 Phosphorous atom(s) - a total of 37 atom(s). The molecular weight of TEPP is determined by the sum of the atomic weights of each constituent element multiplied by the number of atoms, which is calculated to be:

$$ 290.18772 · \frac{g}{mol} $$

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 TEPP Molecule


  • InChI (IUPAC International Chemical Identifier) information of TEPP

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

    InChI=1S/C8H20O7P2/c1-5-11-16(9,12-6-2)15-17(10,13-7-3)14-8-4/h5-8H2,1-4H3

    It can provide a way to encode the molecular information of TEPP 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 TEPP is:

    InChIKey=IDCBOTIENDVCBQ-UHFFFAOYSA-N

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