The number of atoms present in 591 g of gold is 1.81×10²⁴ atoms

Avogadro's hypothesis

From Avogadro's hypothesis,

1 mole of Gold = 6.02×10²³ atoms

But

1 mole of gold = 197 g

Thus,

197 g of gold = 6.02×10²³ atoms

How to determine the atoms in 591 g of gold

197 g of gold = 6.02×10²³ atoms

Therefore,

591 g of gold = (591 × 6.02×10²³) / 197

591 g of gold = 1.81×10²⁴ atoms

Thus, 1.81×10²⁴ atoms is present in 591 g of gold.
