How much electricity in terms of Faraday is required to produce `20 g`

1.	How much electricity in terms of Faraday is required to produce `20 g` of `Ca` from molten `CaCl_(2)` ?
Answer» Correct Answer - 1 Eq. of `Ca, (w)/E = (i xx t)/(96500)` `Ca^(2+) + 2e rarr Ca` `:. E_(Ca) = (40)/(2)` or `(20)/(40//2) = (i xx t)/(96500)` `i xx t = 1 xx 96500 = 1 F`
