Net Charge of a System

  1. Jan 23, 2014 #1
    1. The problem statement, all variables and given/known data

    Find the net charge of a system consisting of 2.0×10^7 electrons.

    2. Relevant equations
    e = 1.60 * 10^-19 C

    3. The attempt at a solution

    (1.60 * 10^-19) * (2.0×10^7) = 3.2 * 10^-10

    ...but I got it incorrect. I'm confused as to how else I'm supposed to solve this.
