Question

sodium crystallizes in a body-centered cubic unit cell calculate the approximate number of unit cells in 9.2 gram of sodium​

Answer 1

Answer:

No of atoms per unit cell for bcc(z)=2

No of atoms in 9.2g of Na

=9.2g23gmol−1×6.022×1023atomsmol−1

=2.4088×1023atoms

No of unit cells =2.4088×1023atoms2atomsunitcell−1

=1.2044×103unitcell
