An antique automobile bumper is to be chrome plated. The bumper, which is dipped into an acidic Cr2O7 2- solution, serves as a cathode of an electrolytic cell. The atomic mass of Cr is 51.996
Q. If oxidation of H2O occurs at the anode, how many moles of oxygen gas will evolve for every 151 grams of Cr(s) deposited? A) 4.36 B) 0.726 C) 17.4 D) 11.6 E) 3.87
