How to get Mass of the structure with stoichiometry data?

hi, we add the coefficient for salt in structure according to the method about adding attached data. please see the attached example. Is there a way to get the mass or exact mass and formula about this kind of structures in jchem database(Jchem version: 5.4.1)? Currently, the Mass and formula didn't take the coefficient in account 

Hi,

I forward the topic to the appropriate group dealing with chemical terms.

Dear Juan,

providing stoichiometry as attached data is not suitable for further calculations with Chemical Terms.

You should use multiple groups in your molecules described here:

The set stoichiometry data will be considered in your calculations this way.
