Can't help because APPARENTLY there is a picture that goes along with the questions. Post it and I can help.
First calculate for number of moles:
moles Ag = 12 g / (107.87 g / mol)
moles Ag = 0.111 mol
Convert to atoms using Avogadros number:
atoms Ag = 0.111 mol * (6.022 x 10^23 atoms / mol)
atoms Ag = 6.7 x 10^22 atoms
There are 47 electrons per atom, therefore:
Number of electrons = (6.7 x 10^22 atoms) * (47 electrons
/ atom)
<span>Number of electrons = 3.15 x 10^24 electrons</span>
