Question

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 100.g Cu?

Answer 1

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

a. how much silver nitrate was there?
b. assuming the reaction goes to completion, ie, there is enough silver nitrate, then you get 2 moles siver for each mole of Cu.

moles Cu=100/atomicmassCu
moles Ag=2* above
grams Ag= above*atomicmassAg

Answer 2

339gAg
