Academics

Simple Cubic Packing when r+ MnO has either 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/cm3. A) Does MnO crystallize in the NaCl or the CsCl type structure? B) Assume the ionic radius of oxygen is 140. pm, estimate the ionic radius of manganese c) Does the calculated cation-to-anion radius ratio for MnO substantiate your answer to part (b)? A) Calculate density based on unit cell and compare with experimental value FCC Volume of unit cell =a3 = (4.47 x 10-8 cm)3 = 8.93 x 10-23 cm3.
