yes.
because mass of electrones (which is set free by Cu) is nearly 0 (extremely small). So scientist consider it as 0.
conclusion : atomic mass of Cu = Cu2+

yes it does.. Mass of an electron is considered negligible.. Therefore the loss or gain of an electron is actually inconsequential for day to day requirements.. However, if you are doing a detailed study of Cu2+ at an atomic or sub atomic level, it would make a considerable difference..
However, like I said earlier, for all practical purposes, it does not matter..

By definition, it does not. It is an ion, not an atom. The mass of that ion is less than the mass of a copper atom by the mass of two electrons.

Yes. Atomic mass is determined by the number of protons and neutrons, whereas the charge "+2" is determined by the number of electrons, or in this case an absence of electrons.

Technically no, because the 2 electrons that are missing DO have a mass, but mathematically it is so small, it's insignificant.

Yes, in terms of general chemistry calculations they have the same mass.

Perhaps.
