The graph between $\log (\frac{x}{m})$ and $\log P$ is provided for the adsorption of $NH_3$ gas on a metal surface. Calculate the weight of $NH_3$ gas adsorbed by $50 \ gm$ of the metal surface at $2 \ atm$ pressure. (in $gm$)

When $200 \, mL$ of $0.2 \, M$ acetic acid is shaken with $0.6 \, g$ of wood charcoal,the final concentration of acetic acid after adsorption is $0.1 \, M$. The mass of acetic acid adsorbed per gram of carbon is $...... \, g$.
