Copper metal (Cu) reacts with silver nitrate (AgNO3) in aqueous solution to form Ag and Cu (NO3) 2. An excess of AgNO3 is present. The balanced chemical equation is shown below.
Cu + 2AgNO3 - - - > Cu (NO3) 2 + 2Ag
The molar mass of Cu is 63.5 g/mol. The molar mass of Ag is 107.9 g/mol. What mass, in grams, of Ag is produced from reaction of 31.75 g of Cu?
26.95
107.9
215.91
431.82
