\( 10 \mathrm{~mL} \) of \( 1 \mathrm{mM} \) surfactant solution forms a monolayer covering \( 0.24 \mathrm{~cm}^{2} \) on a polar substrate, if the polar head is approximated as a cube, what is its edge length?
(a) \( 2.0 \mathrm{pm} \)
(b) \( 2.0 \mathrm{~nm} \)
(c) \( 0.1 \mathrm{~nm} \)
(d) \( 1.0 \mathrm{pm} \)
