Calculate the mass of copper needed to displace 5.0g of silver from silver nitrate solution.

Cu+2AgNO3->Cu(NO3)2+2Ag

(Relative atomic masses:Ag=108,Cu=63.5)

I got it to be 3.175g needed.

• Chemistry -

I can't get 3.175 g. Please post your work. Also, please clarify if the 5.0 is 5.0 g Ag or 5.0 g AgNO3.
