Here is a precise question for the student to solve:A student performed an electroplating experiment of copper metal onto an electrode by passing a constant current of 1.5 A through a solution of copper(II) sulfate for 50 minutes. If the mass of the copper metal obtained was 1.23 grams, calculate the Faraday constant using the following formula: Faraday constant = (mass of substance plated x molar mass of substance) / (current x time)
