Version 3.2 of Molecular Weight Calculator for Windows now available.
New Features: Allows use of abbreviations as custom elements in
formula finder.
For Percent Solver, added display of differences
between target percentages and obtained percentages.
Changed comment delimeter to be a semicolon in the
MWTWIN.INI file and the .DAT files.
Added detection of a mouse click to stop the percent
solver and formula finder.
Why is it better than other programs available? First of all it's
free, yet fully functional. I feel it is very powerful, more functional
and more user friendly than other molecular weight programs I've found
over the net. I'm making it available for others so that they can use it
in their research and studies. Plus, the program is fully Windows 95
compatible (beside Win 3.x). The Dos version is also still available.

As for the Windows version, ...
FEATURES
-----------------------------------------------------------------------------
Multi Line Display Display of up to seven formulas with their molecular
weights simultaneously.
Percent Composition Percent composition of up to seven formulas.
Parentheses Are Allowed Handles up to 4 layers of embedded parentheses.
For example, (CH3)3CH2CH3 is equivalent to CH3CH3CH3CH2CH3.
Hydrates or other appended compounds are allowed.
For example, FeCl3-6H2O.
User-definable abbreviations Default abbreviations are included for common
parts of compounds, including amino acids. See full list.
For example, PhCl = C6H5Cl and HOac = CH3COOH.
Smart Case Conversion The program will automatically convert lowercase
letters to uppercase where appropriate for ease of entering a formula. Exact
case matching and non-conversion are also available.
Edit and save abbreviations while program is running.
Isotopes are recognized using the following notation:
^13C is Carbon-13
C6H5^18OH is heavy-oxygen (Oxygen-18) labeled phenol
Feature of weighting parts of a compound relative to the other parts.
For example,
[.2Na]Cl would have a weight of 0.2*22.989768+35.4527=40.0507
NaCl-[.5H2O] would have a weight of
22.989768+35.4527+0.5*(2*1.00794+15.9994)=67.4501
Percent Solver mode for finding the value of "x" in a compound that satisfies
user-specified percent composition requirements.
Edit and save elemental values while program is running.
Accuracy of the final digit of the molecular wt. and percent composition.
Capability to set optional features at the command line when starting the
program.
Capability of saving options as defaults and automatic loading of the saved
options upon program start.
Easily Cut, Copy, and Paste information between the Molecular Weight Calculator
and other Windows applications.
Mole/Mass Converter for easily translating moles to mass (kg, g, mg, pounds,
ounces) and back.
Formula Finder for finding possible compound empirical formulas for a given
molecular weight or for a given set of percent composition data.
Capability of printing results.
Extensive On-Line Help and Error Checking

About the Author
I am an undergraduate chemistry major at the University of Wyoming in Laramie,
Wyoming. I plan to attend graduate school and aim to obtain a doctorate in
chemistry. I taught myself to program in BASIC on an Apple //c (with 128 Kb
of Ram and no hard disk) in 1986 during 6th grade. Since then, I have updated
to GW-Basic, then QuickBasic v4.5, QuickBasic v7.1 for DOS, and now Visual
Basic 3.0 for Windows. I am familiar with C, and, though I know it is much
faster than Basic, I stick with the various forms of Basic since I am much
more comfortable with the language. I have also been told that Visual Basic
is easier to learn than Visual C, and, in fact, I taught myself Visual Basic
in two days.
