MOLWT  Version 2.72  Updated utilities for chemical calculations

  Do you ever need to do a quick molecular weight calculation from a
  chemical formula, or want to know how many grams of Na2SO4.10H2O
  are in 100 ml of a 0.076M solution? You can use MOLWT, a new shareware
  program, to get instant answers, even at the DOS command-line, and you
  can redirect the results to a printer or disk file.

  MOLWT272.ZIP contains utilities for simple chemical calculations

     There are already some excellent chemical calculation programs,
     including CHEMCALC and MOLARMAS.  MOLWT is not as versatile as 
     these, but it is much faster for what it does do, and it needs 
     a lot less disk space.  It will run on any computer that can
     use DOS.  There isn't a Mac version. Color is used for emphasis, 
     but the screens are legible on any kind of monitor.

    Available by anonymous ftp from  simtel.coast.net  and from SimTel
    mirrors, in the
                    /SimTel/msdos/chemstry directory. 
    The file is molwt272.zip.  (Note spelling of the directory name!)

    Also available from  garbo.uwasa.fi  in the /pc/science directory,
    as molwt272.zip.

    Dont forget to enter the "binary" command before downloading!

    The MOLWT23.ZIP  archive contains 5 files:
    1.  MW.EXE calculates molecular weight from an entered chemical
        formula. Can be used at the DOS command line, or interactively.
        Use DOS redirection to send results to a comma-delimited
        ASCII file. You can build up a database of formulae and their
        moecular weights.
    2.  MW.DOC  Explains what you do. (Gives more examples etc than
        the on-line help system of MW.EXE)
    3.  SOLUTION.EXE gives concentrations in various units in response to
        an entered formula and concentration.  This new version is fully
        stand-alone, and does not use MW.EXE or make any temporary files.
        It can be used at the DOS command line, or interactively.  DOS
        redirection sends (or appends) the results to an appropriately 
        formatted text file.
    4.  SOLUTION.DOC Tells you all about it. (More detail than the
        self-documentation and help messages of SOLUTION.EXE)
           Note that DOS redirection of MW or SOLUTION does not prevent 
           the display of results on the screen. These updated versions 
           also have more unofficial symbol-like abbreviations (for radicals 
           etc.) than the earlier shareware releases. They no longer end
           with messages asking you to pay. The incentive is now the
           provision of extra utilities for "registered" users.
     5. MOLWT.EXE is a self-executing documentation file, which can be read 
        on screen or printed in whole or part.  It tells you about the MW
        and SOLUTION programs, and also about some of the additional utility
        programs that are sent to users who pay the small "registration" fee.
