Answer:

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

Explanation:

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

For redox reactions, we could write:

#Na(s) rarr Na^(+) + e^-#

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

#"Avogadro's number"# is simply a number, admittedly it is a very large number, #6.022xx10^23*mol^-1#.
