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

A

`19.8 mL`

B

`96mL`

C

`8.6mL`

D

`9.6mL`

Text Solution

Verified by Experts

The correct Answer is:
4
Volume of 4 atoms `=a^(3)=(4xx10^(-8))^(3)cm^(3)`
volume of `N_(A)` atoms `=((4xx10^(-8)))/(4)xx6.023xx10^(23)=9.6ml`.
