u take 60 gram of oxygen.
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.
