For the reaction  ${\mathrm{Na}}_{\mathrm{2}}{\mathrm{CO}}_{\mathrm{3}}+2{\mathrm{CH}}_{\mathrm{3}}\mathrm{COOH}\to {\mathrm{CO}}_2+2{\mathrm{CH}}_{\mathrm{3}}\mathrm{COONa}+{\mathrm{H}}_{\mathrm{2}}\mathrm{O}$
Where, atomic masses of $\mathrm{Na}=23\mathrm{u},\mathrm{C}=12\mathrm{u},\mathrm{O}=16\mathrm{u},\mathrm{H}=1\mathrm{u}$  1u how many grams of  ${\text{Na}}_{\text{2}}{\text{CO}}_3$ would be required if 82 g of ${\mathrm{CH}}_3\mathrm{COONa}$  is formed
