Which circult is a serles circult?​

Well to my expert knowledge and my exquisite calculations i think the the negative ion # 412 is the key to sucess

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 !
