qmol
A simple molecular weight calculator
qmol is a simple molecular weight calculator, available for Linux and Windows, derived from Tomislav Gountchev's KMol. You can enter a formula, (e.g. CH3(CH2)2OH) and get its molecular weight (60.0959 g/mol) and its elemental composition (C3H8O: C 59.96; H 13.42; O 26.62 %). See the features list below for more details or consult the wiki page: https://sourceforge.net/p/qmol/wiki/Home/. For Windows binary and source code see the files section: https://sourceforge.net/projects/qmol/files/ Binary packages (rpm/deb) for openSUSE Leap 15.2-42.2, xUbuntu 20.10-19.10, 17.04, Fedora 33, CentOS 8, Scientific Linux 7, and Debian 10.0-8.0 can be found at: http://download.opensuse.org/repositories/home:/lineinthesand/ -

Jljp
Calculates the voltage across a liquid junction between two solutions
An analogous project written in C# can be found here: https://github.com/swharden/JLJP Liquid junction potential calculator. It's a tool for scientists and engineers who have to do with electrochemistry and electrokinetics. When two solutions containing ions are put into contact, possibly through a porous diaphragm, a voltage develops across them. The calculation of the voltage is not trivial. The program is written in Java. Includes classes that can be included in other programs, together with graphical interfaces (also as an applet). -
