The unit cell length of sodium chloride ...

The unit cell length of sodium chloride crystal is 360 pm. Its density would be

A

`4.632 g m^(-3)`

B

`6.267 g m^(-3)`

C

`8.327 g cm^(-3)`

D

`9.732 g cm^(-3)`

Text Solution

Verified by Experts

The correct Answer is:
C
`rho=(NM)/(a^(3)N_(A))=(4xx58.5 g "mol"^(-))/( (360xx10_(m)^(-12))^(3)(6.023xx10^(23) "mol"^(-1)))`
