3.13 How much electricity in terms of Faraday is required to produce
(i) 20.0 g of Ca from molten ?
The equation for the question is given by :-
In this equation, for 1 mol of Ca, 2F charge is required or we can say that for 40 g of Ca charge required is 2F.
So, for 20 g of Ca charge required will be = F = 96500 C.
