Question: how to calculate the number of moles of electrons?
Answer: You can calculate \(F\) by multiplying the charge on one electron (1.602 x 10-19) by Avogadro's number (6.022 x 1023). For this reaction, we would say the number of electrons, \(n\), is two. For every mole of zinc that reacts, it produces two moles of electrons.
