Chemical conversions are a part of nearly every chemical experiment or homework problem. In the Wolfram Language such transformations are done with
ChemicalConvert
.
ChemicalConvert
operates on
ChemicalInstance
objects and handles interconversion between atoms, molecules, amount, mass and volume.

Conversion factors such as density are utilized when present and labeled with the corresponding physical quantity.

The

ChemicalInstance
object itself.
Use the “Amount” subvalue to find the number of moles:

ChemicalConvert and the “Quantity” subvalue produce the same results:
