Molybdenum crystallizes in a body-centered cubic array of atoms. The edge of the unit cell is 0.314
Question:
Molybdenum crystallizes in a body-centered cubic array of atoms. The edge of the unit cell is 0.314 nm long. Calculate the density of this metal.
Strategy
First, determine the net number of atoms per unit cell; then determine the mass using the atomic mass of molybdenum. Divide this mass by the volume of the cubic unit cell, knowing its edge length. Convert the units as necessary to obtain a proper unit for density.
