1-Changing the Atomic Weights and output precision

The Atomic Mass used for calculation of molecular 
weight can be found in file MOLWT.DAT.  This is a 
pure text file and can be edited by MS notepad. 
The first line in this file specifies the number 
of decimals for presentation of the calculated 
results. You may choose anything between 2 and 6 
decimals. The second line is the atomic weight 
of H. The third line is atomic weight of He and 
so on.  The current version of MOLWT.DAT is based 
on data from:

IUPAC Commision on Atomic Weights and Isotopic Abundances.
Pure Appl. Chem., 68, 2339-2359 (1996).

Molecular Weight Calculator is an MS Windows application that 
calculates the molecular weight of any compound by using its 
chemical formula. The application supports all atoms in the 
periodic system. Documentation which is in Windows help format 
is available through the help push button inside the program.
