A) \[\text{1}\text{.76 }\!\!\times\!\!\text{ 1}{{\text{0}}^{\text{-3}}}\text{kg}\]
B) \[\text{9}\text{.67 }\!\!\times\!\!\text{ 1}{{\text{0}}^{\text{-3}}}\text{kg}\]
C) \[\text{17}\text{.61 }\!\!\times\!\!\text{ 1}{{\text{0}}^{\text{-3}}}\text{kg}\]
D) \[\text{3}\text{.67 }\!\!\times\!\!\text{ 1}{{\text{0}}^{\text{-3}}}\text{kg}\]
Correct Answer: C
Solution :
Mass of the substance deposited at the cathode \[m=zit\] \[=z\left( \frac{W}{V} \right)t\] \[=0.367\times {{10}^{-6}}\times \frac{100\times {{10}^{3}}}{125}\times 60\] \[=17.6\times {{10}^{-3}}kg\]
