Question

You are given a small bar of an unknown metal. You find the density of the metal to be 10.5 g/cm3. An X-ray diffraction experiment measures the edge of the unit cell as 409 pm. Assuming that the metal crystallizes in a face-centered lattice, what is the metal most likely to be?

A) Pt
B) Pb
C) Rh
D) Ag
E) None of these

Answer 1

D) Silver.

Step-by-step explanation:

The density and the structure fit the metal silver whose unit cell edge is 407 pm

Answer 2

Ag
