Solution

The correct option is A $18$ mg
$50$ mL of $0.06 N$ acetic acid solution contains $0.06 m o l / L$ $\times \frac{50 m L}{1000 m L / L} \times 60 g / m o l = 0.180 g$ of acetic acid.

After filtration, $50$ mL of $0.042 N$ acetic acid solution contains $0.042 m o l / L \times \frac{50 m L}{1000 m L / L} = 0.126 g$ of acetic acid.

Hence, the amount of acetic acid adsorbed on $3 g$ of activated charcoal is $0.180 g - 0.126 g = 0.054 g$ . This is equal to $54 m g$ .

Hence, the amount of acetic acid adsorbed on $1 g$ of activated charcoal is $\frac{54 m g \times 1 g}{3 g} = 18 m g$ .
