Molar mass calculator computes molar mass, molecular weight and elemental composition of any given compound.
Massa molar e mol Molar mass and molecular weight distribution determination of uhmwpe synthesized using a living homogeneous catalyst.
Molar mass of polyvinyl alcohol by viscosity solvent with no solvating effect which would make the molecular size increase ie the molar mass is m v. Molecular masses are calculated from the standard atomic weights  of each nuclidewhile molar masses are calculated from the mol e massa molar mass of each element.
The atomic mass takes into account the isotopic distribution of the element mol e massa molar a given sample usually assumed to be "normal". For example, water has a molar mass of The distinction between molar mass and molecular mass is important because relative molecular masses can be measured directly by mass spectrometryoften to a precision of a few parts per million.
This is accurate enough to directly determine the chemical formula of a molecule. Please mol e massa molar improve this section by adding citations to reliable sources. Unsourced material may be challenged and removed.

Most atomic masses are known to a precision of at least one part in ten-thousand, often much better  the atomic mass of lithium is a notable, and serious,  exception. This is adequate for almost all normal uses in chemistry: The precision of atomic masses, and hence of molar masses, is limited by the knowledge of the isotopic distribution of mol e massa molar element.
If a more accurate value of the molar mass is required, it is necessary to determine the isotopic distribution of the sample in question, which may be different from the standard distribution used to calculate the standard atomic mass.
The isotopic distributions of the different elements in a sample are not necessarily independent of one another:
