1 gram of activated charcoal has a surface area of $10^3{m}^2$. Complete coverage of the charcoal surface by NH₃ molecules is assumed by monolayer formation. The diameter of each NH₃ molecule is 4 Å. Ammonia is adsorbed on the charcoal by two-dimensional close-packed arrangements with maximum efficiency.

In another experiment, $10\sqrt{3}gm$ of the given charcoal is treated with 100 mL of 5 M ammonia solution. After adsorption, the excess ammonia solution is removed. Given: $N_A=6\times 10^{23}$.
