Consider the reduction reaction
Mn++ne−⟶M
According to Faradays law,
W=‌

If W is the weight of substance deposited.
Since W is given as 1g equivalent, which is equal to ‌

M

n

. Therefore, Q=F.
1F=96500 coulomb of charge = charge on 1 mole of electrons. Therefore, to deposit 1g equivalent of substance l mole of electrons is needed.
