For the titration of a 10 mL (aq) solution of $\mathrm{CaCO}_{3}, 2 \mathrm{mL}$ of $0.001 \mathrm{M} \mathrm{Na}_{2} \mathrm{EDTA}$ is required to reach the end point. The concentration of $\mathrm{CaCO}_{3}$ (assume molecular weight of $\mathrm{CaCO}_{3}=100$ ) is

(a)$5 \times 10^{-4} \mathrm{g} / \mathrm{mL}$

(b)$2 \times 10^{-4} \mathrm{g} / \mathrm{mL}$

(c)$5 \times 10^{-5} \mathrm{g} / \mathrm{mL}$

(d)$2 \times 10^{-5} \mathrm{g} / \mathrm{mL}$
