To find the value of the Faraday constant, we can use the formula:Q = n * Fwhere Q is the charge in coulombs , n is the number of moles of Cu^2+ ions, and F is the Faraday constant.First, we need to find the charge Q passed through the solution. We can use the formula:Q = I * twhere I is the current in amperes and t is the time in seconds .Given that the current is 0.5 A and the time is 15 minutes, we can convert the time to seconds:15 minutes * 60 seconds/minute = 900 secondsNow, we can find the charge:Q = 0.5 A * 900 s = 450 coulombsNow that we have the charge, we can find the Faraday constant using the formula Q = n * F. We know that there are 0.05 moles of Cu^2+ ions, so:450 coulombs = 0.05 mol * FTo find F, we can divide both sides of the equation by 0.05 mol:F = 450 coulombs / 0.05 mol = 9000 C/molSo, the value of the Faraday constant is approximately 9000 C/mol.
