Calculating the Molecular Weight from a Chemical Formula, Common Name, or Protein Sequence

The molecular weight (MW) can be algebraically calculated from any chemical formula that adheres to chemical conventions, with the precise quantity of the significant digits that are reported by state-of-the-art experiments. The ChemW library consists of three packages – ChemMW, Proteins, and PHREEQdb – which are detailed in their respective pages. ChemW is offered with the MIT License. Examples of the module are available in the examples directory of the ChemW GitHub repository. Please submit errors or inaccuracies as GitHub issues so that they may be resolved. An effective Python IDE can be used to execute this module.

Installation

The following command installs ChemW in a command prompt/terminal environment:

pip install chemw
