Conducting objects can be chrome-plated by immersing them in an electrolytic bath having positive chromium ions in solution. Each ion carries a charge of +e, and the object to be plated, say an automobile bumper, is wired as the negative electrode in the bath. A positive electrode is also placed in the bath, and as a current flows between the two electrodes, chromium ions get deposited on the negative electrode (the bumper). If 0.186 kg of chromium is deposited on a bumper in 105 min, what is the current passing through the bath? The molar mass of chromium is 0.0520 kg.
