Version 4.1 of Molecular Weight Calculator for Windows 95 now available.
New Features: Ability to expand abbreviations into their
elemental equivalencies when used in a formula
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. A Windows 3.x and a Dos version of this
program are also available (see below).
AVAILABILITY
------------------------------------------------------------------------------
Windows 95 Version (MWTWin v4.1)
The program is available via the web at http://www.unc.edu/~monroem/ or at
http://www.simtel.net/pub/simtelnet/win95/chem/ in the mwt4_1.zip file.
The program is also available via Anonymous FTP at ftp.simtel.net under
pub/simtelnet/win95/chem/ in the mwt4_1.zip file, and ftp.ccl.net under
the pub/chemistry/software/MS-WINDOWS95/Molecular_Weight/ directory in
the mwt4_1.exe file.
To save space, the mwt4_1.zip and mwt4_1.exe files do not contain the
MSVBVM50.DLL file and do not contain an install program; instead,
directions for installation are included in the Readme.Txt file.
MSVBVM50.DLL can be downloaded from various sites on the WWW, including:
http://www.simtel.net/simtel.net/win95/dll.html
under vb5run.zip
http://www.sharepaper.com/apps/reviews/q_ufad.html
under Visual Basic 5 Runtimes
http://www.softseek.com/Utilities/VBRUN_Files/
under VB5 Runtime Files
http://www.apexsc.com/vb/davem/vbttdl.html
under VB 5 Runtime Files
You can also ftp the file from various sites, including:
ftp.simtel.net/pub/simtelnet/win95/dll/msvbvm50.zip
OAK.Oakland.edu/pub/simtelnet/win95/dll/msvbvm50.zip
ftp.uoknor.edu/mirrors/simtelnet/win95/dll/msvbvm50.zip
ftp.coast.net/SimTel/win95/dll/msvbvm50.zip
Windows Version (MWTWin v3.2)
The program is available via the web at http://www.unc.edu/~monroem/ or
at http://www.coast.net/SimTel/win3/chem.html and
http://www.cdrom.com/simtel.net/win3/chem.html and
http://www.simtel.net/pub/simtelnet/win3/chem/ in the mwt3_2.zip file.
The program is also available via Anonymous FTP at ftp.coast.net under the
SimTel/win3/chem/ directory in the mwt3_2.zip file, at ftp.simtel.net under
pub/simtelnet/win3/chem/ in the mwt3_2.zip file, and ftp.ccl.net under the
pub/chemistry/software/MS-WINDOWS/Molecular_Weight/ directory in the
mwt3_2.exe or mwt3_2s.exe files.
Dos Version (MWT v2.87)
The program is available via the web at http://www.unc.edu/~monroem/ or
at http://www.coast.net/SimTel/msdos/chemstry.html and
http://www.cdrom.com/simtel.net/msdos/chemstry.html and
http://www.simtel.net/pub/simtelnet/msdos/chemstry/ in the mwt2_87.zip file.
The program is also available via Anonymous FTP at ftp.coast.net under the
SimTel/msdos/chemstry/ directory in the mwt2_87.zip file, at ftp.simtel.net
under pub/simtelnet/msdos/chemstry/ in the mwt2_87.zip file, and ftp.ccl.net
under the pub/chemistry/software/MS-DOS/Molecular-Weight-Calculator/
directory in the mwt2_87.exe file.
As a final option, I can mail you a UUEncoded or MIME encoded version
via e-mail; just drop me a line.
Please see my home page for the Windows 3.x and Dos version features.
As for the Windows 95 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 in mwtwin.hlp
file. Additionally, the abbreviations can be expanded into the elemental
equivalencies when used in a formula.
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. You can also use the mole/mass converter for molarity
related calculations.
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 (including context sensitive tool tips) and
Error Checking

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, Visual Basic 3.0 for Windows,
and now Visual Basic 5.0 for Windows
