24.1.2—The relationship F = Le between the Faraday question 1
[Maximum number: 1]
An electrolytic cell is set up to determine a value for the Avogadro constant, L. The electrolyte is dilute sulfuric acid and both electrodes are copper.
When a current of 0.600 A is passed through the acid for 30.0 minutes, the anode decreases in mass by 0.350 g .
State the relationship between the Faraday constant, F, and the Avogadro constant, L.
F=LeOR F is directly proportional to L
