A unit of cell of sodium chloride has four formula units. The edge length of the unit cell is `0.564 nm`. What is the density of sodium chloride?

A

`1.2 g// cm^2 `

B

`2.165 // cm^3 `

C

`3.64 g// cm^2`

D

`4.56 g // cm^3 `

Text Solution

Verified by Experts

The correct Answer is:
B
`"Density"=(nM)/(N_A xx a^3)`
`=(4 xx 58.5)/(6.023xx 10^23xx(5.64 xx 10^(-8))^3)=2.17 g//cm^3 `
