Molecular Weight Description

The METHANESULFONIC ACID molecule consists of 4 Hydrogen atom(s), 1 Carbon atom(s), 3 Oxygen atom(s), and 1 Sulfur atom(s) - a total of 9 atom(s). The molecular weight of METHANESULFONIC ACID is determined by the sum of the atomic weights of each constituent element multiplied by the number of atoms, which is calculated to be:

$$ 96.10566 · \frac{g}{mol} $$

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 METHANESULFONIC ACID Molecule


  • InChI (IUPAC International Chemical Identifier) information of METHANESULFONIC ACID

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

    InChI=1S/CH4O3S/c1-5(2,3)4/h1H3,(H,2,3,4)

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

    InChIKey=AFVFQIVMOAPDHO-UHFFFAOYSA-N

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