How many gram of cobalt metal will be deposited when a solution of cobalt (II) chloride is electrolyzed with a current of 10 amperes for 109 minutes (1 Faraday = $96, 500 C$ ; Atomic mass of $Co = 59 u$ )NEET 2013 (Karnataka)

Options:

Answer:

Solution:

$W = \frac{I t E}{96500} = \frac{10 \times 109 \times 60 \times 59}{96500 \times 2} = 19.99 \approx 20 g$
