Vcls Submit Provide FeedbackExplanation / Answer
mass of sodium = W= 1000Kg
molar mass of sodium = 23.0grams/mole = 0.023 Kg/mole=M
valency of Soidum = Z=1
current = C= 2.50x10^4 A
Faraday = F = 96500 coloubs
according to faradays laws
W= Mct/ZF
1000 = 0.023x2.50x10^4xt/1x96500
t= 46.618 hours.
Time required for the production of Na= 46.618 hours
Part-B
molar mass of Cl2 = 71 grams
valency = Z=1
c=2.50x10^4A
time= 46.619=8 hours= 46618.36 sec
W=Mct/ZF
W= 71 x2.50x10^4x46618.35/1x96500=857487.78 grams
mass of Cl2 formed= 857487.78 grams
At STP one mole of gas occupies 22.4 L of volume
i.e 71 grams of Cl2 occupies = 22.4 L
857487.78 grams of Cl2 = ?
= 22.4x857487.78/71=270531.35L
volume of Cl2 = 270531.35L
