Most precise volume of HCl = 5 ml

at equivalence point,

\text { Meq. of } \mathrm{Na}_{2} \mathrm{CO}_{3}=\text { meq. of } \mathrm{HCl}

Let molarity of Na2CO3 solution = M, then

\mathrm{M} \times 10 \times 2=0.2 \times 5 \times 1

\mathrm{M}=0.05 \mathrm{~mol} / \mathrm{L}\mathrm{=0.05\ M}

\mathrm{\mathrm{M}=0.05 \times 1000 \ mM}

\mathrm{\mathrm{M}=50 \ mM}

 Ans = 50
