In 5 g atom of Ag(At wt of Ag = 108), calculatethe weight of one atom of Ag-

Answer»

Ag has atomic mass of 108 which is equal to its 1 mole.

Acc to avagadro number 1 mole has 6.O23×10^23 atoms . Which means 108 g of Ag contains 6.023×10^23 atoms.

Therefore 5 g of silver will have : O.28 × 10^23 atoms.

ok thanks
