In fact we can use $moles$ $"moles"$ to measure all of these species.

Explanation:

The answer they probably wanted you to give was to exclude $electrons$ $"electrons"$ . Nevertheless, we can certainly measure electrons using molar quantities.

For redox reactions, we could write:

$N a (s) \to N a^{+} + e^{-}$ $Na(s) rarr Na^(+) + e^-$

And if a $23 \cdot g$ $23*g$ mass of sodium metal is oxidized, certainly $Avogadro's number of electrons$ $"Avogadro's number of electrons"$ are evolved.

$Avogadro's number$ $"Avogadro's number"$ is simply a number, admittedly it is a very large number, $6.022 \times 10^{23} \cdot m o l^{- 1}$ $6.022xx10^23*mol^-1$ .
