How Do You Calculate the Specific Charge of a Cu2+ Ion?

[bullseye]

Stuggling with this idea..

A Cu atom loses two electrons, for the ion formed calculate its specific charge in C kg ^-1.

Please could you show working.

Many thanks

What is the net charge of the Cu ion, in coulombs, after it has lost the two electrons?

What is the mass of a Cu ion, in kg?
