The number of electrons delivered at the cathode, during electrolysis by a current of $1 ampere in 60 seconds$ is (charge on electron $= 1.60 \times 10^{- 19} C$ )NEET 2016 (Phase 2)

Options:

Answer:

Solution:

$Q = I \times t$
$= 1 A \times 60 s$
$= 60 C$

$∴$ Number of electrons $= \frac{60}{1.602 \times 10^{- 19}}$

$= 3.75 \times 10^{20}$
