An element has bcc packing with a body-centered cubic unit cell. Its density is 19300 kg/m3 and the unit cell volume is 3.17 x 10-26 L. Calculate the molar mass (g/mol) of the element to three significant figures.

3. Calculate the volume of a unit cell of KCl (assume NaCl unit cell). From this, calculate the density of KCl and compare it with the observed value of 1.98 g/cm. em²

Metallic palladium crystallizes in a face-centered cubic lattice, with one Pd atom per lattice point. If the edge length of the unit cell is found to be 388 pm, what is the metallic radius of Pd in pm? r = pm

The element zirconium has hcp packing with a hexagonal unit cell. The volume of the unit cell is 4.66 x 10-26 L. Calculate the density (kg/m3) of the element.

Calculation of lonic Radii The edge length of the unit cell of LiCl (NaCl-like structure, FCC) is 0.514 nm or 5.14 Å. Assuming that the lithium ion is small enough so that the chloride ions are in contact, as in Figure 10.60, calculate the ionic radius for the chloride ion. Note: The length unit angstrom, Å, is often used to represent atomic-scale dimensions and is equivalent to 10-10 m.
