CBSEENCH12011477
Wired Faculty App

 A cubic unit cell of a metal with a molar mass of 63.55 g mol-1 has an edge length of 362 pm. Its density is 8.92 g cm-3. The type of unit cell is

  • Primitive

  • Face centred

  • End centred

  • Body Centred

Solution

B.

Face centred

Density = Z X Ma3 x NAz = d x NA x a3M = 8.92 x 6.023 x 1023 x (362 x 10-10)363.55 = 4∴  The metal crystallises in fcc.
