I've added some error handling to
https://test2.wikipedia.org/wiki/Module:Molar_mass_calculator for you; most
likely it was trying to use a quantity of empty-string for any elements you
didn't specify in your Chembox, which tonumber() converts to nil. You could
probably also have had your Chembox pass 0 as a default (e.g. {{{Ag|0}}}
instead of {{{Ag|}}}).
If it's still not working, feel free to put your test cases on test2wiki so
we can see them directly.
