Assume each aluminum atom supplies one conduction An aluminum wire having a cross-sectional area equal to 5.60 x 10'6 m electron per atom. Find the drift speed of the electrons in the wire. x The equation for the drift velocity includes the number of charge carriers per volume, which in this case is equal to the number of atoms per volume. How do you calculate that if you know the density and the atomic weight of aluminum? mm/s Need Help? _ 2. [0/1 Points] PREVIOUS ANSWERS SERPSE10 26.1 .OP.004. ASK YOUR TEACHER PRACTICE ANOTHER A teapot with a surface area of 535 cm2 is to be plated with silver. It is attached to the negative electrode of an electrolytic cell containing silver nitrate (Ag+ NO3'). The cell is powered by a 12.0-V battery and has a resistance of 1.90 0. If the density of silver is 1.05 x 104 kg/m3, over what time interval does a 0.133mm layer of silver build up on the teapot? x You first need to calculate the total number of silver atoms contained in the plated volume of silver. Note that the nitrate ends up on the other electrode. h Need Help
