Correct option is (c) 6.02 x 1024
The total number of electrons present in 18 ml of water is 6.023 × 1024.
Number of electron in one molecule of H2O is 2 + 8 = 10.
Density = 1 g/ml
∴ 18 ml means 18 g
Moles = \(\frac {18}{18}\) = 1
Molecules = 6.023 × 1023
Electrons = 6.023 × 1023 × 10 = 6.023 × 1024
