Category:Chem-molar-mass both hardcoded and calculated

Populated by Chem molar mass/format. That template can take a value in any of several different parameters; this category tracks when more than one is passed. It is called via Chem molar mass from Infobox drug. In that context, it tracks pages that have a molecular formula specified by individual element parameters (.........), which triggers the template to auto-calculate the molecular weight, when there is also an explicit molecular_weight value.
