A solid compound is formed by atoms of A (cations), B (cations) and O (anions). Atoms of O form hcp lattice. Atoms of A occupy 25\% of tetrahedral holes and atoms of B occupy \(50 \%\) octahedral holes. What is the molecular formula of solid?
- A \(\mathrm{AB}_2 \mathrm{O}_4\)
- B \(\mathrm{ABO}_3\)
- C \(\mathrm{ABO}_2\)
- D \(\mathrm{A}_2 \mathrm{BO}_4\)
Answer & Solution
