10 ml of 1 millimolar surfactant solution forms a monolayer covering `0.24cm^(2)` on a polar substrate.
If the polar head is approximated as a cube. Consider the surfactant is adsorbed only on one face of the cube. What is the edge length of cube? (Answer should be in pm and assume Avogadro's number `=6xx10^(23)` ).

A

1.0 pm

B

0.1 nm

C

2.0 nm

D

2.0 pm

Number of particles `=10^3/10^2 N_A`
Total area= Area covered by one particle `times` number of particle of 0.24 =`AS_10`
`At2`
(a) edge length =210
