Example 1	iron(II) oxide (Q196680) contains chemical element iron (Q677) → 1, oxygen (Q629) → 1
Example 2	dumortierite (Q677619) contains chemical element aluminium (Q663) → 7, boron (Q618) → 1, silicon (Q670) → 3, oxygen (Q629) → 18

quantity (P1114) not usable as 1. it is integer only 2. for non-molecular compound, this number is actually a proportion, not a count. GZWDer (talk) 17:51, 11 October 2019 (UTC)[reply]

Comment I don't see a fundamental difference between your two proposals here, it should be just a single property, with Quantity value. ArthurPSmith (talk) 18:13, 14 October 2019 (UTC)[reply]
- As both properties are qualifiers, and qualifiers on qualifiers are not supported, two qualifiers are needed.--GZWDer (talk) 10:47, 19 October 2019 (UTC)[reply]
Comment Another reason to have just one is that empirical values are not strictly speaking for the compound or substance, but whatever you had in your sample (which also included impurities). Also for simple organic compounds, the integers are in experimental conditions also not integers. We round them for practical means to match our idea of chemical graphs better. I'm more in favor of having one with rational number values. Where they can simply be 1.0. --Egon Willighagen (talk) 05:31, 15 October 2019 (UTC)[reply]
