MHT CET 2024 Chemistry question

Not in JEE Main or NEET syllabus

Calculate the molar mass of an element having density that forms bcc structure.

Answer: (B)

For a cubic unit cell, density , so . A bcc structure has 8 corner atoms plus 1 body-centre atom, so . Substituting, \dfrac${5.6\ g cm^{-3} × 75\
