1. Data table of molecular weight of common materials

The molar mass of a substance, also often called molecular mass or molecular weight (although the definitions are not strictly identical, but it is only sensitive in very defined areas), is the weight of a defined amount of molecules of the substance (a mole) and is expressed in g/mol. It can be calculated by adding the invididual molar mass of every atom that are composing the molecule (CH4 : 1 atom of C -> molar mass = 12.011 g/mol + 4 atom of H -> molar mass = 1.008 g/mol -> molar mass of CH4 = 12.011+4*1.008=16.043 g/mol)

Please find below a table of common compounds and their molar mass, aggregated from different sources (warning : values were not verified individually). Please scroll down, the compounds are sorted alphabetically ; or use the Ctrl+F function to find what you are looking for.
