Electrons in GRAMS :( 1. The problem statement, all variables and given/known data Part1: A sample of electrons is found to have a total charge of -7.68 x 10^8 C. How many electrons are in this sample ? =================================== Part 2 says: What is the mass of the above sample of electrons in grams ? 2. Relevant equations 1 electron mass = 9.10938188 × 10^-28 grams] 3. The attempt at a solution for part 1 My answer was 4.79e27. And its CORRECT for part 2 i keep getting 4.36 as an answer but its wrong. I used [1 electron mass = 9.10938188 × 10^-28 grams] and multiplied that by my answer for part 1. PLEASE HELP, Thanks.
