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.
