Calcium crystallizesin `fcc` unit cell with `0.556 nm`. Calculate the density if
a. It contains `0.2%` Frenkel defects
b. It contains `0.1%` Schottky defects

A

`1.90 g//cm^(2)`

B

`1.54 g//cm^(2)`

C

`3.4 g//cm^(2)`

D

`5.4 g//cm^(2)`

Text Solution

Verified by Experts

Thus, density can be determined using `d=(2M)/(a^(2)N_(0))`
d( with V ocance defect ) = `(3.996xx40)/((0.556xx10^(-7))^(2)xx(6.02xx10^(22)))= 1.5448 g// cm^(3)`
