For the reaction $\displaystyle \mathrm{A} \rightarrow$ products. The concentration of A at $\displaystyle 10$ minutes is $\displaystyle \_\_\_\_$ $\displaystyle \times 10^{-3} \mathrm{~mol} \mathrm{~L}^{-1}$ (nearest integer). The reaction was started with $\displaystyle 2.5 \mathrm{~mol} \mathrm{~L}^{-1}$ of A .
