Problem: The density of solid Ag is 10.5 g/cm3. How many atoms are present per cubic centimeter of Ag?As a solid, Ag adopts a face-centered cubic unit cell. How many unit cells are present per cubic centimeter of Ag?What is the volume of a unit cell of this metal?What is the edge length of a unit cell of Ag?

FREE Expert Solution

a) Given: density of Ag = 10.5 g/cm3 → 1 cm3 of Ag has a mass of 10.5 g

Atomic mass of Ag = 107.67 g/mol


# of atoms=10.5 g Ag1 cm3×1 mol Ag107.67 g Ag×(6.022×1023 atoms)1 mol Ag


# of atoms = 5.87 × 1022 Ag atoms/cm3


There are 5.87 × 1022 Ag atoms per cubic centimeter.
