Question on Calcium Sulfide structure

The diagram represents the unit cell for a crystal of calcium sulfide, CaS(s), which has the sodium chloride structure. The radii of the ions are: rCa2+ = 106 pm and rS2- = 184 pm.

a) Calculate the edge length of the CaS unit cell (in pm) b) Calculate the mass of one unit cell of CaS (in g) c) Calculate the density of CaS(s) (in g/cm3) d) Calculate the minimum distance (in pm) between the edges of two S2- ions within the unit cell of CaS"

What students and professors have to say

It's been an amazing experience being able to use Kipin Hall. The service has really kicked my academic career into full speed. Studying and collaborating is super fun with this platform. I really wouldn't know what to do without it now.
