Calculate the time required to deposit an even layer of gold 1.20脳10^鈭? cm thick on the object.?

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 49.9 cm^2 and the density of gold is 19.3g /cm^3. A current of 3.20 A is applied to a solution that contains gold in the + 3 oxidation state.|||(49.9 cm^2)(1.20e-3 cm)(19.3 g Au/ cm^3)(mol Au/ 196.97 g Au)(3 mol e-/ mol Au)(96485 C/mol e-)(s / 3.20 C) = 531 s or 8.85 min.
