An amp is a Coulomb per second, so you can set up a conversion 

$$\Bigg( \frac{8A}{} \Bigg) \Bigg( \frac{1 C}{1 s}\Bigg) \Bigg( \frac{1 e^-}{1.6\times10^{-19}C}\Bigg) = \frac{\# \ e^{-}}{s} $$

$$I = \frac{ Q }{ \Delta t }$$

$$I \Delta t = Q$$

$$\frac{ Total charge }{ charge per electron} = number of electrons$$
