Correct answer
341
Step-by-step explanation
Benzyl Amine is most basic due to localised lone pair.
Mole of benzyl Amine mole 1 Mole of Benzyl amine consumed 1 mole of HCl So, Mole of HCl consumed mole Mass of HCl consumed molar mass of HCl $\begin{aligned} & =0.00934 \times 36.5 \\ & =0.341 \mathrm{gm} \\ & =341 \mathrm{mg} \end{aligned}$
