(b) A metal bromide,MBr2, is converted to a molten form at hightemperatures. Electrolysis of this sample with a currentof 6.20 A for 74.9 seconds results indeposition of 0.153 g of metal M at the cathode. Theother product is bromine gas, Br2(g), which isreleased at the anode. Determine the identity of metal M.
