\begin{aligned} & \text { Power }=100 \mathrm{KW} \\ & \text { Voltage }=125 \mathrm{~V} \\ & \text { Power }=\mathrm{Vi} \\ & 100 \times 10^3=125 \mathrm{i} \\ & \mathrm{i}=\frac{100000}{125} \\ & \mathrm{i}=800 \mathrm{A} \end{aligned}

We know that first law of electrolysis

\begin{aligned} & m=\text { Zit }(\mathrm{Z}=\mathrm{E} . \mathrm{C} . \mathrm{E}) \\ & =\frac{0.367}{1000} \times 10^{-6} \times 800 \times 60 \\ & =367 \times 48 \times 10^{-6} \\ & =17616 \times 10^6 \mathrm{~kg} \\ & =1.76 \times 10^{-2} \mathrm{~kg} \end{aligned}
