Number of moles of benzoic acid$=\frac{0.2}{122}=1.64\times 10^{-3}$
Neutralization takes place as
$2{\mathrm{C}}_6{\mathrm{H}}_5\mathrm{C}\mathrm{O}\mathrm{O}\mathrm{H}+\mathrm{B}\mathrm{a}(\mathrm{O}\mathrm{H}{)}_2\to ({\mathrm{C}}_6{\mathrm{H}}_5\mathrm{C}\mathrm{O}\mathrm{O}{)}_2\mathrm{B}\mathrm{a}+2{\mathrm{H}}_2\mathrm{O}$
Number of moles of$\mathrm{B}\mathrm{a}(\mathrm{O}\mathrm{H}{)}_2$required$=\frac{1}{2}\times 1.64\times 10^{-3}$
$\frac{\mathrm{M}\mathrm{V}}{1000}=\frac{1}{2}\times 1.64\times 10^{-3}$
$\frac{0.12\times \mathrm{V}}{1000}=\frac{1}{2}\times 1.64\times 10^{-3}$
V = 6.83 mL
