The metal chromium crystallizes in a body-centered cubic lattice.If the density of chromium is 7.14 g/cm³,what is the unit cell edge length?

Question

Quizplus · Accepted Answer

The density formula for a body-centered cubic lattice is: Density = (2 * atomic mass) / (a^3 * Avogadro's number). Solving for 'a' using chromium's atomic mass (51.996 g/mol) and given density (7.14 g/cm³), the unit cell edge length 'a' is approximately 289 pm.
