Concept

Problem: MnO has either the NaCl type structure or the CsCl type structure. The edge length of the MnO unit cell is 4.47 x 10-8 cm and the density of MnO is 5.28 g/cm 3. Assuming that the ionic radius of oxygen is 140. pm, estimate the ionic radius of manganese.

FREE Expert Solution

We need to identify the type of structure of MnO by determining how many atoms are present on the MnO unit cell.

Given:

Edge length (a) = 4.47x10-8 cm
 Density = 5.28 g/cm3

Let’s first calculate the volume of the unit cell:
