Answer:
Each SO2 molecule contains 2 atoms of oxygen. Therefore, the number of oxygen atoms is twice the number of SO2 molecules. 3. The sample of SO2 contains 0.253 mol x (6.022 x 1023
Also 1 molecule of SO2 consists of 3 atoms ( 1 of Sulphur and 2 of oxygen). So, 1 mole of SO2 = 6.023× 10^23 molecules of SO2 = 3× (6.023× 10^23) atoms = 18.069× 10^23 atoms.
