							Sol. (a) 1eq. mass of the substance requires 96500 coulombs
Since the element is monoatomic, thus eq. mass = mol. Mass
6.023 × 10^23 atoms require 96500 C
1 atoms require 96500/6.023 *10^23 C = 1.6 * 10^-19 C
(b) Since the element is diatomic eq.mass = (1/2) mol.mass
∴ (1/2) * 6.023 * 10^23 atoms 2eq. 96500C
⇒ 1 atom require = 96500 * 2/6.023 * 10^23 = 3.2 * 10^-19 C
