A hypothetical ionic compound AB ( mol. ...

A hypothetical ionic compound `AB ( mol. Wt. =240 g//mol e)` , having co`-` ordination number of anion equal to 6, has a closest anion`-` anion distance of `4sqrt(2)A`. Determine the density of ionic compound `AB` in `gm//c c`

A

`6.24`

B

`3.12`

C

`1.56`

D

`0.78`

Text Solution

Verified by Experts

The correct Answer is:
2
`d=(ZxxM)/(N_(A)a^(3))=(4xx240)/(6.02xx10^(23)xx8^(3)xx10^(-24))=3.12`
