Uma peça de metal de formato irregular feita de uma liga particular foi galvanizada com zinco usando uma solução de Zn(NO₃)₂. Quando uma corrente de 2,70 A foi usada, levou exatamente 1 hora para depositar uma camada de 0,015 mm de zinco na peça. Qual é a área total de superfície da peça? A densidade do zinco é de 7,14 g /cm³. Suponha que a eficiência seja 100%. MM (Zn) = 65,4 g/mol; 1 mol e = 96500 C.
