If you go thorough and assign oxidation numbers to each atom on both sides, you'll see that Cu(s) is oxidized to Cu2+ ions and the N of HNO3 is reduced from a +5 oxidation state to a +4 oxidation state in NO2(g). Within the balanced equation, 3 Cu atoms are oxidized, each gives up 2 electrons, so a total of 6 moles of electrons are transferred.
