A copper and a chromium voltmeter are connected in series with a battery. It found that in half an hour

0.475\,\,g

of copper and

0.130\,\,g

of chromium have been deposited. The ECE ratio of copper and chromium is

View answer and explanation

Correct option: C

\begin{array}{llllllllllllllllllll} {\mathrm{3}\mathrm{.65}} \end{array}

Option C (3.65) is correct because the ratio of ECE is directly proportional to the ratio of the masses deposited, as the current and time are the same.
