An element crystallizes in a body-centered cubic lattice, with a = 4.109 Å. If the element has a density of 9.95 g·cm^-³, what is the molar mass of the element?

Question

Quizplus · Accepted Answer

In a body-centered cubic lattice, there are 2 atoms per unit cell. The volume of the unit cell is (4.109 x 10^-8 cm)^3. Using the density formula and Avogadro's number, the molar mass is calculated to be approximately 208 g·mol^-1.
