Use {{chem2}} to simplify markup

New page

{{Documentation subpage}}
This template calculates the '''[[molecular mass]]''' (or molar mass) of a chemical compound. It is designed to be embedded in infoboxes {{tl|Infobox drug}} and {{tl|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:
<code><nowiki>{{Chem molar mass|H=2|O=1}}</nowiki></code> (for {{chem2|H2O}}) → {{Chem molar mass|H=2|O=1}}

:{{para|round}}
:{{para|unit}}

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

{{para|'''ref'''|<ref>some source</ref>}} will add the reference right after the unit.

{{para|'''comment'''|Any text}}is added as a suffix, after a space and unedited (no brackets added etc.).

Example:
:<code><nowiki>{{Chem molar mass|fixed=234.56 g·mol−1|ref=<ref>Some source</ref>|comment=My Comment}}</nowiki></code> → {{nowrap|1={{Chem molar mass|fixed=234.56 g·mol−1|ref=<ref>Some source</ref>|comment=My Comment}}}}

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

== Blank parameter list ==

==Standard atomic weights used==
{{Chem molar mass/testtable}}

===Data sources (CIAAW) ===

Primarily, the atomic weights used here are defined by [[CIAAW]] [http://www.ciaaw.org/publications.htm]:
* {{cite web|title=Standard Atomic Weights|url=http://www.ciaaw.org/atomic-weights.htm|author=|date=2015|accessdate=2015-09-20|publisher=[[Commission on Isotopic Abundances and Atomic Weights]] (CIAAW)}} (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).
:{{cite web|title=Atomic weights of the elements 2013 (xls) |url=http://www.ciaaw.org/publications.htm |first1=T.B.|last1=Coplen|first2=W.A.|last2=Brand|display-authors=1|date=2013 |accessdate=2015-05-26|publisher=CIAAW}}
* 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 {{tl|Drugbox}}. The molecular formula can be entered like <code>...|H=2|O=1</code>, and these values then are passed through to this subtemplate, together with the other parameters like <code>|round=</code>.

==Units==
*{{para|unit}}
:1. When some {{para|unit|kg/mol}} is used, it is added as is, always ("by the editor").
:2. When {{para|fixed}} is used, no unit is added to this (could be in it already).
:3. When {{para|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]]: [{{val|1.00784}}, {{val|1.00811}}] is calculated using conventional: 1.008(0)
===Calculate cumulative uncertainties===
* {{cite web|url=https://www.degruyter.com/view/j/pac.2018.90.issue-2/pac-2016-0402/pac-2016-0402.xml|accessdate=2019-02-08|date=2018-01-04|title=Interpreting and propagating the uncertainty of the standard atomic weights (IUPAC Technical Report)|first1=Antonio|last1=Possolo|first2=Adriaan M.H.|last2=van der Veen|first3=Juris|last3=Meija|first4=D.|last4=Brynn Hibbert}}

* {{clc|Articles with erroneous molar mass calculations}}
* {{clc|Pages using Chem molar mass with unsupported parameters}}
