1.67x10^23 atoms
Explanation:
From Avogadro's hypothesis, 1mole of any substance contains 6.02x10^23 atoms.
This means that 1mole of gold contains 6.02x10^23 atoms.
1 mole of gold = 197g
197g of gold contains 6.02x10^23 atoms.
Therefore, 54.5g of gold will contain = (54.5 x 6.02x10^23) / 197 = 1.67x10^23 atoms
