Q125 / 200 · NEET 2006 · Physics
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:
- A$13.6 \mathrm{mg}$
- Correct answerB$17.6 \mathrm{mg}$
- C$21.3 \mathrm{mg}$
- D$24.3 \mathrm{mg}$
Solution
Mass of chlorine liberated $=2 \mathrm{It}$
$$
\begin{aligned}
& =0.367 \times 10^{-6} \times \frac{100}{125} \times 60 \\
& =0.0176 \times 10^{-3} \mathrm{~kg} \\
& =17.6 \mathrm{mg}
\end{aligned}
$$
Hence, the correct answer is option: 'B'.
