When copper metal is added to silver nitrate in solution, silver metal and copper (II) nitrate are produced. What mass of silver is produced from 200.g Cu?

Answer 1

Cu(s) + 2AgNO₃(aq) ==> Cu(NO₃)₂ + 2Ag(s) ... balanced equation for the reaction taking place

200.g Cu x 1 mol Cu/63.55 g x 2 mol Ag/mol Cu x 107.9 g Ag/mol = 679 g Ag (3 sig.figs.)
