The field of nanotechnology offers some intriguing possibilities, such as the creation of fibers one atom wide. Suppose you were able to string together 1.00 mol Ag atoms, each of radius 144 pm, into one of these fibers by encapsulating them in carbon nanotubes. How long would the fiber extend?

Answer 1

1 mole of Ag atoms contains 6.02*10^23 atoms (Avogadro's number). Multiply that by twice the radius (244*10^-12 m)to get the length of the nanotube.

Answer 2

1.7x10^14?

Answer 3

1.73x10^11 km
