According to "Webelements", molar mass of Ag = 107.87 g/mol
No. of moles of Ag = (53.91 g) / (107.87 g/mol) = 0.4998 mol
No. of moles of Ag = (53.91 g) / (107.87 g/mol) = 0.4998 mol

Ag is 107.9 g/mol
53.91 g / 107.9 g/mol = 0.4998 mol
53.91 g / 107.9 g/mol = 0.4998 mol

Each mole of silver atoms is 107.87 grams. That should be enough of a hint so you can figure the answer.
