Chemistry Assistant
ver. 1.6 for Win95/98/NT
Split, October 1999.

PURPOSE

Chemistry Assistant is a program for fast calculation of molar mass of compounds by simple entry of chemical formula. The program translates the texts with chemical element symbols or without them into a mathematical expression and calculates them. Chemistry Assistant contains comprehensive list of physical constants and SI Units.



USAGE

Chemistry Assistant translates the chemical formulae into mathematical text, and replaces the element symbols with their atomic mass. The appearance of mathematical expression which is the result of the translation can be seen if the mouse pointer is held over the entry field. For example,

H2SO4  becomes  H*2+S+O*4  i.e. 1.00794*2+32.066+15.9994*4

The element symbols can be written in lowercase letters, and the program will try to translate them and will show the result of translation in the entry field - or it will report an error. The right mouse button has several often used anions and molecules.

The (...) key will put the selected text or the whole expression into parentheses in the entry field.
Negative numbers are obtained by putting the character [-] before the number, (2*-3=-6.)
Double multiplication [**] is replaced by raising to power [^], (2**3=2^3=8).
The root is obtained by raising the number to the reciprocal value of the root (1/x); for example, third root of 8 is 8^(1/3)=2.
Clicking on the result can change the type of display of result, (1000 => 1.00E+03).

All of the calculations can be saved and recalled again, or a new calculation can be read from disk. The program reads and calculates line by line, ignoring all that appears after the equal sign (=).

CONTENTS OF THE DISTRIBUTION PACKAGE


The distribution package (chemas16.zip) contains the following files:

 readme.txt		- this document
 procitaj me	- this document on Croatian language
 File_id.diz	- short program description
 example.tsk	- sample calculations which can be imported
 chemas.exe		- the calculation program itself
 Astronom.con	- astronomy constants 
 Physical.con	- physical constants
 Prefix.con		- prefixes of SI units
 Units.con		- SI units

You'll also need the files msvbvm50.dll and comdlg32.ocx, which are not in the package.



INSTALLATION

Unpack (unzip) the chemas16.zip file into a directory you'll use for the program. There is no additional installation procedure.

In order for the program to work, you need to have the files MSVBVM50.DLL and COMDLG32.OCX in the ../Windows/System directory (those are core libraries for programs written in Visual Basic 5.0). Those files are not included in the package, but if you don't have them already, you can download them in a ZIP format from:

	http://www.ktf-split.hr/~eni/toys/msvbvm50.zip

	http://www.ktf-split.hr/~eni/toys/comdlg32.zip



DEINSTALLATION

Simply delete the files from disk.



The author shall not be responsible for any damages, direct or indirect, which may result from the use of this software.
