ထႅမ်းပလဵတ်ႉ:Chem molar mass

ၽိုၼ်ၵႅမ်မိုဝ်းထႅမ်းပလဵတ်ႉ[တူၺ်း] [မႄးထတ်း] [ပိုၼ်း] [ၸၢင်း]

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.

(to be documented, 2019-02-09)

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

Primarily, the atomic weights used here are defined by CIAAW [1]:

• Standard Atomic Weights. Commission on Isotopic Abundances and Atomic Weights (CIAAW) (2015). Retrieved on 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).

Atomic weights of the elements 2013 (xls). CIAAW (2013). Retrieved on 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.

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=.

• |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 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)
