Q55.Atoms of element X form hcp lattice and those of element Y occupy 32 of its tetrahedral voids. The percentage of element X in the lattice is (Nearest integer)
What This Question Tests
This question tests the understanding of crystal structures, specifically the hcp lattice and the occupation of its tetrahedral voids, to determine the percentage composition of elements.
Concepts Tested
Formulas Used
