How long does it take to pass a current of force I = 1.8 A through a solution of silver salt so that a layer of silver with a thickness of h = 0.058 mm is deposited on N = 12 spoons, serving as a cathode and having a surface area S = 50 cm2 each? The density of silver is p = 10.5 • 103 kg/m3, the molar mass of silver is M = 108 • 10-3 kg/mol, its valency n = 1. Faraday's constant F = 9.65 • 104 C/mol.
