- Purpose: Chemistry related scientific software
-
- To calculate the molecular weight of a compound
- from its chemical formula
-
- Status of software: Freeware (although small donations are
- always welcome when requesting upgrades)

- This application provides interactive help when the !Help
- application (or !Bubblehelp) is active, and requires Risc OS
- 3.1 or later.

- What this software does
-
- It calculates from a molecular formula the molecular
- weight, and also the mass of the compound corresponding to a
- selected number of millimoles. The percentage elemental
- composition can be displayed, and the user may also define
- their own groups for use in calculations. Formulae are
- entered in a way as near to the conventional method of
- writing formulae as is consistent with the standard WIMP
- interface. For example, methane is C1H4, and toluene (methyl
- benzene) could be entered either as C7H8, or as C6H5C1H3.

-
- Running the application
-
- As a fully RISC-OS compliant application it can be started
- from within the desktop by double clicking on the !MolWeight
- icon in a directory viewer. Its icon is installed on the
- iconbar. Clicking with SELECT on the iconbar icon opens a
- window into which the formula can be entered, and the
- results of the calculation are displayed. The program
- normally uses average atomic weights for the calculations,
- but it is also possible to use exact values of isotopic
- atomic weight for a range of common isotopes. Since the
- program allows you to enter your own data, any particular
- isotope can be accommodated.
-
- Use the on-line help for more information once the
- application is running.
