How many grams of Cu (s) are needed to form 6.00g Ag from a solution of AgNO3?
The reaction is Cu (s)+2Ag^+(ag)--> Cu^2+(aq)+2Ag (s) the molar masses are: Ag=107.868 and Cu=63.546g

mols Ag in 6.00g = grams/atomic mass
mols Cu = 1/2 mols Ag (from the coefficients in the balanced equation)
Then g Cu = mols Cu x atomic mass Cu
