Copper metal (Cu) reacts with silver nitrate (AgNO3) in aqueous solution to form Ag and Cu(NO3)2. The balanced chemical equation is shown. Cu plus 2 AgNO sub 3 rightarrow Cu open paren NO sub 3 close paren sub 2 plus 2 Ag The molar mass of Cu is 63 point 5 g over mol The molar mass of Ag is 107 point 9 g over mol What mass, in grams, of Ag is produced from a reaction of 31 point 7 5 g of Cu ?
