A strip of zinc metal was placed in a beaker that contained 120mL of a solution of copper(2) nitrate, Cu(NO3)2(aq). The mass of the copper produced was 0.813g. Find the initial concentration of the solution of copper(2)nitrate.

Can u help me out with making the balanced chemical equation and stating the gives and unknowns then I will try to do the rest..hmm... lets see if I get it right this time:D

Thanks!!

  1. Zn + Cu(NO3)2 ==> Zn(NO3)2 + Cu
    You know grams Cu produced which should allow you to calculate the mols Cu(NO3)2 initially.
    You now know mols, you want mols/L for M.
