MHT CET Chemistry question
Not in JEE Main or NEET syllabus
A compound formed by elements X and Y crystallizes in the cubic structure, where X is at the corners of the cube and Y is at the six face centres. What is the formula of the compound? If side length is 5 Å, estimate the density of the solid assuming atomic weight of X and Y as 60 and 90 respectively
Answer: (B)
Solution
X: and Y: , so the formula is (rules out (a) and (d)); $M = 60 + 3 × 90 =
