What is the charge (Coulombs) of a nanogram of electrons?

    1. The problem statement, all variables and given/known data
    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

    2. Relevant equations


    3. The attempt at a solution

    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:
