Problem 85P
Iron crystallizes in a body-centered cubic structure. The volume of one Fe atom is 8.38 × 10−24 cm3, and the density of Fe is 7.874 g/cm3. Find an approximate value for Avogadro's number.
ANSWER:
Solution 85P
Here we have to find an approximate value for Avogadro's number.
Step 1
Iron crystallizes in a body-centered cubic structure.
Volume of one Fe atom = 8.38 × 10−24 cm3
Density of Fe = 7.874 g/cm3 but Fe atoms occupy only 68 % of the volume in a body-centered cubic cell.
