Question

uestion 2: (16 points) agnesium oxide (Mg0) has the rock salt crystal structure and a ensity of 3.58 g/cm2. The atomic weights of magnesium doxygen are 24.31 g/mol and 16.00 g/mol, respectively. Using the information above, determine the unit cell edge length. etermine the unit cell edge length from the radii in the table below assuming that ns just touch each other along the edges. Ionic Radius (nm) Ionic Radius (nm) Anion Cation Mg2 Fe2 Na 0.181 0.072 0.140 02 0.077 0.102
