Reference no: EM13719620

Question- A thin layer of gold can be applied to another material by an electrolytic process. The surface area of an object to be gold plated is 49.9cm2 and the density of gold is 19.3g/cm3. A current of 3.20A is applied to a solution that contains gold in the +3 oxidation state.

Calculate the time required to deposit an even layer of gold 1.20×10?3cm thick on the object.

Give me complete explanations of above question thus I can get high score
