Answer: 24 atoms
Step-by-step explanation:
Atomicity is the total number of atoms present in a molecule.
In sulfur dioxide (SO2), there is one sulfur atom and two oxygen atoms present. So, the total number of atoms is 3. It means that SO2 has atomicity 3. Hence, the number of atoms present in SO2 molecule are 3. Therefore in 8 SO2 molecules /8x3 = 24). Hence, 24 total atoms in 8 SO2
