The correct option is B 128 moles
24.088×1023 SO2 molecules =24.088 × 10236.022 × 1023 moles = 4 moles of SO2
The number of electrons in one molecule of SO2=16+(8×2)=32 electrons.
So, the number of moles of electrons in one mole of SO2=32 moles
Therefore, the total number of moles of electrons in 4 moles of SO2 = 128 moles
