An element (atomic mass \( =100 \mathrm{u} \) ) having bcc
\( \mathrm{P} \)
structure has unit cell edge \( 400 \mathrm{pm} \). The density of
W
the element is:
(A) \( 2.144 \mathrm{~g} / \mathrm{cm}^{3} \)
(B) \( 5.2 \mathrm{~g} / \mathrm{cm}^{3} \)
(C) \( 7.289 \mathrm{~g} / \mathrm{cm}^{3} \)
(D) \( 10.376 \mathrm{~g} / \mathrm{cm}^{3} \)
