an irregularly shaped metal part was made from a particular alloy was galvanized with zinc using a Zn(NO3)2 solution. When a current of 1.95 A was used, it took exactly 1.7 hours to deposit a 0.0267-mm layer of zinc on the part. What was the total surface area of the part? The density of zinc is 7.410 g/cm^3. Assume the efficiency is 100%. Calculate your answer to at least 2 decimal places.
