What happens if you overheat copper sulfate

If  you  overheat  copper  sulfate  higher  of   mass  will  be  lost that  is  copper  sulfate  will  loss  sulfur  and  oxygen which  led to a  higher loss  of  mass than  if  you  would   have heated enough. This  higher  mass lost will  be shown  in  calculation  as  percentage of  water  lost

Since there is the same amount of agn03 in both silver chloride and silver nitrate they produce the same amount of moles. therefore silver chloride produces the same amount of silver nitrate, so your answer is 15.0 moles of silver nitrate. i hope this !
