molar mass of oxygen is 16 grams, it means that 1 mole oxygen weighs 16 grams.
therefore 64 gram oxygen = 64/16 = 4 mole oxygen.
1 mole of any element contains 6.022 * 10^23 atoms in it.
therefore no. of moles in 24.088 * 10^23 atoms = 24.088 * 10^23 / 6.022 * 10^23 = 4 moles
hence 4 moles of oxygen.
therefore 64 gram oxygen = 64/16 = 4 mole oxygen.
1 mole of any element contains 6.022 * 10^23 atoms in it.

molar mass of oxygen atoms=16u
given mass=64 grams
no of moles=given mass/molar mass
=64/16
=4
hence the no of moles in 64 grams of oxygen is 4 moles
