Explanation:

According to Avogadro's law, the Gram Molecular Weight (G.M.W) of a substance contains 6.022*10^23 molecules.

The Gram molecular weight of oxygen = 32 g

Therefore, 32 g of oxygen contains 6.022*10^23 molecules

1 g oxygen contains =6.022*10^23/32 molecules

64 g oxygen contains = 6.022*10^23*64/32 = 12.044*10^23 molecules

Therefore 64 g of oxygen contains = 1.2044*10^24 molecules or 12.044*10^23 molecules

Hope my answer helps you.
