An fcc lattice has a lattice parameter `a = 400` pm. Calculater the molar volume of the lattice including all the empty space.

A

92.3 mL

B

50 mL

C

42 mL

D

38.5 mL

Text Solution

Verified by Experts

Volume of a lattice `a^(2) = (4xx10^(-8))^(2) cm ^(3)`
Molar volume = `(4xx10^(-8)) xx6.023xx10^(23) = 38.5` m1
