Are there not EIGHT avocadoes....

Explanation:

The oxygen atom has 6 valence electrons, 8 electrons in total, and of course since #Z=8#, this assures electrical neutrality.

And so we gots a mole of oxide anions...and each oxide ion has EIGHT valence electrons...if there is a #1 *mol# quantity of oxide anions, there are .....................

#6.022xx10^23*mol^-1xx8*"mol electrons"-=48xx10^23*"electrons"#
