To calculate the Faraday constant, we can use the following formula:Faraday constant F = I * t / n * m where:I = current in amperes t = time in seconds n = number of moles of electrons transferred per mole of substance for copper, n = 2, as the reaction is Cu + 2e Cu m = mass of substance deposited in grams First, we need to convert the time from minutes to seconds:5 minutes * 60 seconds/minute = 300 secondsNext, we need to find the number of moles of copper deposited:The molar mass of copper Cu is approximately 63.5 g/mol. moles of Cu = mass of Cu / molar mass of Cumoles of Cu = 0.3 g / 63.5 g/mol 0.0047 molNow we can plug the values into the formula:F = 2.5 A * 300 s / 2 * 0.0047 mol F 79545.74 C/molThe Faraday constant is approximately 79,546 C/mol.
