Detailed Solution

One mole means $6.02 \times 10^{23}$ entities.

One gram atom of carbon -12 means one mole of carbon-12.

Hence, there is $6.02 \times 10^{23}$ no. of C-12 atoms present.

Similar way, 1 mol of $O_{2}$ gas has Avogadro’s number of $O_{2}$ molecules.

$1 mol of electrons = 6.023 \times 10^{23} e^{-} s$
