The Question and answers have been prepared Can you explain this answer? for Clis part of Class 12 preparation. How many grams 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) a)0.66b)4.0c)20.0d)40.0Correct answer is option 'C'. Therefore, the mass of cobalt metal deposited is 40.1 grams.

Substituting the values in the equation, we get: Number of Faradays passed (n) = 0.678 Faradays M is the molar mass of the substance in grams per mole (g/mol) M is the mass of the substance in grams (g) The number of moles of cobalt (Co) deposited can be calculated using the equation: Therefore, the number of Faradays passed (n) can be calculated as: We know that 1 Faraday is equal to 96,500 C. Substituting the values in the formula, we get: First, we need to calculate the charge (Q) passed through the electrolyte using the formula:
