Template:Chem molar mass/format

Template documentation[view] [edit] [history] [purge]

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 H₂O) → 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]:

"Standard Atomic Weights". Commission on Isotopic Abundances and Atomic Weights (CIAAW). 2015. Retrieved 2015-09-20. (68 elements)
CIAAW also published additional lists in spreadsheet format (2013). It has additional conventional values for trade usage, and some background information on the numbers and calculations. (12 elements: B, Br, C, Cl, H, Li, Mg, N, O, S, Si, Tl).

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: A_r(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)

Calculate cumulative uncertainties
