1B. Gold is the most ductile of all metals. For example, one
gram of gold can be drawn into a wire 2.12 km long. The density of
gold is 19.3 ✕ 103 kg/m3, and its resistivity
is 2.44 ✕ 10−8 Ω · m. What is the resistance of such a
wire at 20.0°C?

If 3.50 ✕ 10−3 kg of gold is deposited on the negative electrode of an electrolytic cell in a period of 2.83 h, what is the current in the cell during that period? Assume the gold ions carry one elementary unit of positive charge. (answer in mA)
Gold is the most ductile of all metals. For example, one gram of gold can be drawn into a wire 2.08 km long. The density of gold is 19.3 x 103 kg/m2, and its resistivity is 2.44 × 10-8 ?·m, what is the resistance of such a wire at 20.0°C? Your response differs from the correct answer by more than 10%. Double check your calculations. MII
