ah yeah that's what I meant just a type in the end, it should have the MW of Ag. k I follow your idea, the separation, the math, I have one last question though. The material is an alloy with 2 metals, so it's chemical equation is something like Ag2Cu?
so I would have to write
Ag2Cu + NaCl ----> AgCl(s) + Na2Cu
Na2Cu + Li3PO4 ---> Cu3(PO4)2 (S) + NaLi
is that it for the chemical equations?
