Find the total electric charge

  1. Sep 1, 2004 #1
    I am confused by a question related to me about electric charge. How can you find the total electric charge of 1 kg of an electron or proton? I know the magnitudes of the charges are + - 1.60X10^-19 C. Would I use the, for example, the electron mass 9.11X 10^31 kg, take the 1 kg and divide by the electron mass? This cancels the kg and then multiply by the electric charge? Please help.

    Sounds good to me. Do a similar calculation for the proton, which has a different mass.

    (The electron mass is 9.11E-31 kg, not 9.11E+31; careful with those exponents! I assume it's just a typo.)
