Calculation of moles of acetic acid adsorbed per cm2 of charcoal surface:

Given:
Surface area of charcoal = 100 m2/g
Amount of charcoal used = 1 g
Amount of acetic acid adsorbed = 60 mg

Step 1: Convert surface area from m2/g to cm2/g
Surface area of charcoal = 100 x 104 cm2/g

Step 2: Convert amount of acetic acid adsorbed from mg to moles
Molecular weight of acetic acid (CH3COOH) = 60 g/mol
Amount of acetic acid adsorbed = 60 mg = 0.06 g
Number of moles of acetic acid adsorbed = 0.06 g / 60 g/mol = 0.001 mol

Step 3: Calculate the surface area of charcoal used
Surface area of charcoal used = surface area of charcoal x amount of charcoal used
= 100 x 104 cm2/g x 1 g
= 100 x 104 cm2

Step 4: Calculate the moles of acetic acid adsorbed per cm2 of charcoal surface
Moles of acetic acid adsorbed per cm2 of charcoal surface = Number of moles of acetic acid adsorbed / Surface area of charcoal used
= 0.001 mol / 100 x 104 cm2
= 106 mol/cm2

Therefore, the correct answer is option B) 106.

Moleculer mass of acetic acid =60 gm/mol.60 AcoH get absorbed means( 60 gm/60 gm/mol)=1 mol AcoH.100 m^2 =10^6 cm^2 surface area. In 10^6 cm^2 area 1 mol AcoH is absorbed In 1 cm^2 area 10^-6 mol AcoH is absobed. Option b is right.
