Problem

1 g charcoal show chemical adsorption of some acetic acid on coming in contact with 100 mL of 0.50 M acetic acid and the molarity of acetic acid is reduced to 0.49 M. If surface area of charcoal is 3.015×102 m2/g3.015 \times 10^2 \text{ m}^2/\text{g} , the surface area of each chemically adsorbed molecule of acetic acid is : (1) 3.015×10−2 m23.015 \times 10^{-2} \text{ m}^2 (2) 5×10−19 m25 \times 10^{-19} \text{ m}^2 (3) 2.5×10−19 m22.5 \times 10^{-19} \text{ m}^2 (4) 1.25×10−19 m21.25 \times 10^{-19} \text{ m}^2
