what is the volume of a face centred cubic unit cell, when its density is 2 g/cm3 and the molar - Chemistry - The Solid State

Question

what is the volume of a face centred cubic unit cell, when its
density is 2 g/cm3 and the molar mass of the substance
is 60 23g/mol?

Avni · Accepted Answer

â€‹It is a 
FCC structure , so the value of Z = 4

Molar mass 
= 60 23 g
density = 2 gcm-3

Volume of unit cell, a3  = Molar mass×Zdensity×NAVolume of unit cell, a3= 60
23×42×6
022×1023                               =20
0033×10-23 cm3
