The electro chemical equivalent of an element is 0.0006735 g/C. Its equivalent weight is

Faraday's Law of Electrolysis states
The equivalent weight is 96500 times greater than the substance's electrochemical equivalent.
In the event that a substance's electrochemical equivalent is 0.0006735,
then multiplying it by 96500 is used to calculate its equivalent weight.

$i.e., 96500\times 0.0006735=64.99\simeq 65g$
