You have purified an enzyme using a series of chromatographic methods. It was observed that a $10 ~\mu \mathrm{g} \mathrm{~mL}^{-1}$ of this purified enzyme converted $10$ mM substrate per hour at $25^{\circ} \mathrm{C}$ and pH $7$. Its specific activity is $\_\_\_\_$ $\mathrm{IU} \mu_{\mathrm{g}}{ }^{-1}$. (rounded off to three decimal places)
