One crystalline form of silica (sio2) has a cubic unit cell, and from x-ray diffraction data it is known that the cell edge length is 0.700 nm. if the measured density is 2.32 g/cm3, how many

(a) si4+ and

(b) o2- ions are there per unit cell? the atomic weights of si and o are, respectively, 28.09 g/mol and 16.00 g/mol.
