In producing chlorine through electrolysis 100 watt power at $125 \mathrm{~V}$ is being consumed. How much chlorine per minute is liberated ? E. C. E. of chlorine is $0.367 \times 10^{-6} \mathrm{~kg} /$ coulomb:
  1. $13.6 \mathrm{mg}$
  2. $17.6 \mathrm{mg}$
  3. $21.3 \mathrm{mg}$
  4. $24.3 \mathrm{mg}$

Solution

Mass of chlorine liberated $=2 \mathrm{It}$ $\begin{aligned} & =0.367 \times 10^{-6} \times \frac{100}{125} \times 60 \\ & =0.0176 \times 10^{-3} \mathrm{~kg} \\ & =17.6 \mathrm{mg} \end{aligned}$
