What is the charge of a nanogram of electrons? This was a test question for me. I didn't know the exact definition of a coulomb, so I guessed about 1. something C. The options were 1.something C, 0.03C, or like 3.64C. Someone care to explain/help? thanks

Under the Relevant Equations section, you should list the mass of an electron and the charge on an electron. Try using that approach and show us what you get... :smile:
 
But I don't wannaaaaaa. Can't you just do it for me and tell me the answer?! :)
