Calculate the number of atoms in

100 g of silver (Ag).

The number of atoms is, The atomic

mass of

Covert gram to mole silver is

= gram/atomic mass or weight 107.868

= 100 g/(107.868 g/mol) g/mol.

= 0.927059 mol

Number of atoms

= (atoms in mole) Avogadro’s constant

23
= (0.927059 mol )(6.022  10 atoms/mol)
= 5.58  10 atoms
