One decides to take a silver nitrate solution and add copper wire to it to produce a pure silver ring. He decides to use a 12.75g peice of copper wire and put it into a solution containing 46.00g of silver nitrate.
a) Did he add enough silver nitrate to comeplete displace the copper? Provide calculations to support your answer.
b) if not, how much more is required to be added? If so, how what mass was of silver nitrate remains in solution?
Cu(s) + 2AgNO3(aq) -- 2Ag(s) + Cu(NO3)2 (aq)

@mos1635 the question im asked is did he add enough silver nitarte to completely displace the copper.   to completely displace the copper, copper would have to be the limiting reactant in this case than, is that right ?
