Molecular Weight Calculator

This is a small program for the calculation of molecular weight from the molecular formula. The features included in this software are: molecular weight calculation from molecular formula and elemental composition calculation; calculate weight (gram) to mmol and vice versa conversion; calculate reagent weight for the entire reaction. IUPAC recommended (1999) Standard atomic weights are used. For radioactive elements atomic mass of long-lived isotope is used. First 103 elements are included. Standard formula notations are accepted. C6H6O is legal while c6h6o is not recognized now. Brackets are supported. CuSO4(H2O)5 is equal to CuSO9H10.
