*Molar Mass Calculator*
This calculator you can use for computing the average molecular weight (MW) of molecules by entering the chemical formulas (for example C3H4OH(COOH)3 ). Or you can choose by one of the next two option-lists, which contains a series of common organic compounds (including their chemical formula) and all the elements. The molecular mass calculator will recognize the entered formula's, which are included in the list of organic compounds.The calculator handles at most two different bracket levels. Make sure you enter the molecule of crystallization at last (e.g. C2HCl3O.H2O )
