    A metal has bcc structure and the edge length of its unit cell is \[3.04\,\,\overset{o}{\mathop{A}}\,\]. The volume of the unit cell in \[c{{m}^{3}}\] will be  

    A)  \[1.6\times {{10}^{-21}}c{{m}^{3}}\]

    B)  \[2.81\times {{10}^{-23}}c{{m}^{3}}\]

    C)  \[6.02\times {{10}^{-23}}c{{m}^{3}}\]

    D)  \[6.6\times {{10}^{-24}}c{{m}^{3}}\]

    Correct Answer: B

    Solution :

    Volume of the unit cell                 \[={{a}^{3}}\]                 \[=\,{{(3.04\times {{10}^{-10}})}^{3}}\]                 \[=\,2.81\times {{10}^{-29}}{{m}^{3}}\] \[=\,2.81\times {{10}^{-23}}c{{m}^{3}}\]
