58. Solving a chemistry problem
441. When a current of 2 A is passed for 1 hour 14 min 24 s through an aqueous solution of metal (II) chloride, a metal weighing 2.94 g is released on one of the graphite electrodes. What is the atomic mass of the metal if the current efficiency is 100% and what kind of metal. Write the equations for the reactions taking place on the electrodes.
