Solution

$A B C$ $A B C$ type of packing pattern is present in FCC unit cell.
$Z_{e f f} = 4$
No. of moles of unit cell= $\frac{3}{4} = 0.75$
No. of tetrahedral void present in one unit cell= $8$
Total no. of tetrahedral voids in $0.75$ mole unit cell= $0.75 \times 8$
= $6$ moles of tetrahedral voids
