1.	A compound formed by elements `X` and `Y` crystallises in a cubic structure in which the `X` atoms are at the corners of a cube and the `Y` atoms are at the face centres.The formula of the compound isA. `XY_(3)`B. `X_(3)Y`C. `XY`D. `XY_(2)`
Answer» Correct Answer - 1 Exclusively contribution `X` atoms per unit cell `=8xx(1)/(8)=1` Exclusive contribution of `Y` atoms per unit cell `=6xx(1)/(2)=3` Simplest whole number ratio of atoms is `1:3` Hence the empirical formule is `XY_(3)`.
