    A) \[24.16\times {{10}^{23}}\]    

    B) \[36.18\times {{10}^{23}}\]

    C) \[6.04\times {{10}^{23}}\]

    D) \[12.08\times {{10}^{23}}\]

    Correct Answer: A

    Solution :

    [a] There are two atoms in a bcc unit cell. So, number of atoms in \[12.08\times {{10}^{23}}\] unit cells \[=2\times 12.08\times {{10}^{23}}=24.16\times {{10}^{23}}\]atoms.
