A metallic element exists as cubic lattice. Each edge of the unit cell is \( 4.0 \AA \). The density of the metal is \( 6.25 \mathrm{~g} / \mathrm{cm}^{3} \). How many unit cells will be present in \( 100 \mathrm{~g} \) of the metal?
(a) \( 1.0 \times 10^{22} \)
(b) \( 2.5 \times 10^{23} \)
(c) \( 5.0 \times 10^{23} \)
(d) \( 2.0 \times 10^{23} \)
