Define homogenous mixture.

A compound is formed by two elements $\mathrm{X}$ and $\mathrm{Y}$. Atoms of element $\mathrm{Y}$ form hexagonal close packing (hcp) lattice and those of the elements $\mathrm{X}$ occupy $(2/3{)}^{\mathrm{rd}}$ of tetrahedral voids. The formula of the compound formed by the elements $\mathrm{X}$ and $\mathrm{Y}$ is
