Template documentation

This template calculates the molecular mass (or molar mass) of a chemical compound. It is designed to be embedded in infoboxes {{Infobox drug}} and {{Chembox}}, but it can be used in-line just as well.

Rounding and uncertainty

(to be documented, 2019-02-09)

Parameters

Use chemical symbols to compose the molecular formula: {{Chem molar mass|H=2|O=1}} (for H
2
O
) → 18.015 g·mol−1

|round=
|unit=


The next parameters will always show:
|fixed= to enter a fixed (predefined) value+unit. It will overwrite any calculated value+unit.

|ref=<ref>some source</ref> will add the reference right after the unit.

|comment=Any textis added as a suffix, after a space and unedited (no brackets added etc.).

Example:

{{Chem molar mass|fixed=234.56 g·mol<sup>−1</sup>|ref=<ref>Some source</ref>|comment=My Comment}}234.56 g·mol−1[1] My Comment

|sortable=yes, for use in sortable tables: will add a hidden sortable number, and omits the unit (see table below).

Data sources (CIAAW)

Primarily, the atomic weights used here are defined by CIAAW [2]:

Coplen, T.B.; et al. (2013). "Atomic weights of the elements 2013 (xls)". CIAAW. Retrieved 2015-05-26.
  • Some unstable elements can naturally occur, and so are listed (4 elements: Bi, Th, Pa, U)
  • Additional values are those of the most stable isotopes, as given in List of chemical elements (34 elements). This source is not supported by the CIAAW publications.

Embedding in a template

The template is designed to be embedded in a template like {{Drugbox}}. The molecular formula can be entered like ...|H=2|O=1, and these values then are passed through to this subtemplate, together with the other parameters like |round=.

Units

  • |unit=
1. When some |unit=kg/mol is used, it is added as is, always ("by the editor").
2. When |fixed= is used, no unit is added to this (could be in it already).
3. When |sortable= is used, no unit is added by the template (expected: put in top of table column).
4. When value is calculated, unit g/mol is added by template.
5. There is automatic no conversion from g to kg.

Uncertainty handling

  • Uncertainty is ignored.
Calcium: Ar(Ca) being 40.078(4) is read and calculated as 40.078(0)
  • Elements having interval notation are calculated by their conventional value.
Hydrogen: [1.00784, 1.00811] is calculated using conventional: 1.008(0)
