$\underset{100\mathrm{g}}{\mathrm{C}\mathrm{a}\mathrm{C}{\mathrm{O}}_3}+\underset{2\times 36.5=73\mathrm{g}}{2\mathrm{H}\mathrm{C}\mathrm{l}}\to \mathrm{C}\mathrm{a}\mathrm{C}{\mathrm{l}}_2+{\mathrm{H}}_2\mathrm{O}+\mathrm{C}{\mathrm{O}}_2$
As 100 g of$\mathrm{C}\mathrm{a}\mathrm{C}{\mathrm{O}}_3$requires 73 g of HCl
So 50 g of$\mathrm{C}\mathrm{a}\mathrm{C}{\mathrm{O}}_3$requires$=\frac{73}{100}\times 50=36.5$g of HCl
