Fischl, a scientist from Mondstadt specializing in electrochemistry, performed an electrolytic cell experiment on an unknown metal solution. She was able to deposit 15.73 g of the metal as solid on the cathode after applying a 1.500 A current for 5.000 hours. Her assistant, Oz, had previously noted that 2 electrons are involved per mole of the metal deposited.  Determine the molar mass of the unknown metal in g/mol. What is the identity of the unknown metal? Cd, Cr, Sr or Mn?
