If the volume occupied by a unit cell of \( \mathrm{NaCl} \) is \( 4.7 \times 10^{-23} \mathrm{ml} \), then the volume of a crystal of \( \mathrm{NaCl} \) weighing \( 1.0 \mathrm{~g} \) is
(a) \( 2.13 \times 10^{22} \mathrm{ml} \)
(b) \( 8.03 \times 10^{-25} \mathrm{ml} \)
(c) \( 0.48 \mathrm{ml} \)
(d) \( 0.12 \mathrm{ml} \)
