The percentage of unoccupied volume in simple cubic cell is

A

0.524

B

0.32

C

0.476

D

0.6804

Text Solution

Verified by Experts

The correct Answer is:
C
`= ("Volume of one atom")/("volume of cubic unit cell") xx 100%`
For simple cubic cell,
packing effeciency `= ((4)/(3) pi r^(3))/(8 r^(3)) xx 100 = 52.4%`
`:.` Percentage of unoccupied volume in Scc
= 100-52.4 = 47.6%
