Question

An atom of rhodium has a diameter of about 2.7×10^-8 cm. . How many Rh atoms would have to be placed side by side to span a distance of 8.5μm?

Answer 1

we are given a total distance of 8.5μm in which the diameter is equal to 2.7 x10^-8 cm. In this case, we convert wach length to m. The one is 8.5*10-6 while the other is equal to 2.7*10^-10. in this case, we fivide the larger by the two. the answer should be 31483 atoms
