A compound is formed by atoms of A, B and C. Atoms of C form hcp lattice. Atoms of A occupy 50 % of octahedral voids and atoms of B occupy 2 3 rd of tetrahedral voids. What is the molecular formula of the solid?

Step-by-step solution

hcp contribution i.e (C)=4 Total octahedral void =4 A contribute =4 50 %=2 Total tetrahedral void =8 B^ 'contribute =8 2 3 = 16 3 aligned & A₂ B_ 16 / 3 C₄ & A₆ B₁₆ C₁₂ aligned By simplify we get A ₃ ~B ₈ C ₆
