Question

number of mole of tetrahedral voids present in FCC type structure having 3 moles f atom is​

Answer 1

Answer:

ABC ABC type of packing pattern is present in FCC unit cell.

Zeff=4

No. of moles of unit cell=43=0.75

No. of tetrahedral void present in one unit cell=8

Total no. of tetrahedral voids in 0.75 mole unit cell= 0.75×8

=6 moles of tetrahedral voids
