Possible Issues  (3)Common pitfalls and unexpected behavior

If the molar mass of a chemical entity cannot be determined, ChemicalConvert remains unevaluated:

In[3]:=3
✖
https://wolfram.com/xid/0n4jk2bfe0k-nddusu
Out[3]=3

If properties of a chemical at a nonstandard temperature and pressure are unavailable, ChemicalConvert remains unevaluated:

In[1]:=1
✖
https://wolfram.com/xid/0n4jk2bfe0k-bdie08
Out[1]=1

Multiple physical quantity keys can lead to unexpected results. Here, the "Mass" key has higher precedence than "Volume", so it is used for the conversion and the results replace the initial volume:
