Molecular Weight Description
The Tetraethyl pyrophosphite molecule consists of 20 Hydrogen atom(s), 8 Carbon atom(s), 5 Oxygen atom(s), and 2 Phosphorous atom(s) - a total of 35 atom(s). The molecular weight of Tetraethyl pyrophosphite is determined by the sum of the atomic weights of each constituent element multiplied by the number of atoms, which is calculated to be:
$$ 258.18892 · \frac{g}{mol} $$
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.
