A mole of SO3 contains 6.0225 * 10^23 molecules. (Avagadros number)
One SO3 molecule has 3 O atoms
Thus a mole of SO3 contains 3 * 6.0225 * 10^23 Oxygen atoms = 18.0675 * 10^23 Oxygen atoms

Remeber SO3 is having three O atoms
one mole SO3 = 6 x 10 ^ 23 molecules of sulphur and oxygen

1 sulphur trioxide molecule contains 3 oxygen atoms.
therefore 1 mole of sulphur trioxide contains 3*6.023*10^23 atoms.(1 mole = 6.023*10^23 units)
